Electric shock is the effect produced on the body and particularly on the nervous system by an electrical current passing through it. The effect depends on the current strength which itself depends on the voltage and body resistance.
Failing to take the necessary precautions can lead to:
- injury or death
- fire or property damage
Common causes of electrocution are:
- Making contact with overhead wires
- Undertaking maintenance on live equipment
- Working with damaged electrical equipment - extension leads, plugs and sockets
- Using equipment affected by rain or water ingress
There are four main types of electrical injuries:
-Electrocution (death due to electrical shock)
-Electrical Shock
-Burns
-Falls
An arc flash happens when electric current flows through an air gap between conductors.
ARC BLAST
• Arc-blasts occur from high- amperage currents arcing through the air.
This can be caused by accidental contact with energized components or equipment failure.
• A DANGEROUS PRESSURE WAVE
• A DANGEROUS SOUND WAVE
• SHRAPNEL
• EXTREME HEAT
• EXTREME LIGHT.
ELECTRIC CURRENT
• Caused by the motion of electrons
• If channeled in a given direction, a flow of electrons occurs.
Severity of the shock depends on:
Path of current through the body
Amount of current flowing through the body Length of time the body is in the circuit

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.
Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
2. What is Electricity?
• Electricity is an invisible phenomenon
created by the movement of electrons in a
conductor.
3. ELCTRON THEORY:
• Electron theory states all matter is comprised
of molecules, which is turn are comprised of
atoms, which are again comprised of protons,
neutrons and electrons.
• A molecule is the smallest part of matter which
can exist by itself and contains one or more
atoms.
5. Electrical Materials
• A material that contains many free electrons and
is capable of carrying an electric current is called
a conductor. Metals and (generally) water are
conductors. Gold, silver, aluminum and copper
are all good conductors.
• Materials that contain relatively few free electrons
are called insulators. Non-metallic materials such
as wood, rubber, glass and mica are insulators.
• Fair conductors include the human body, earth,
and concrete.
10. Safety to be followed at site
Safety
• Sign boards/ Warning Indications should be placed wherever necessary.
• Should use Proper PPE while attending any installation/ maintenance/
troubleshooting
Safety
• PPE (Personal Protection Equipment) includes fall protection, arc flash protection,
fire rated clothing, gloves, boots, and protective eyewear, among other items
• All personnel working on or near PV systems should be trained to recognize
hazards and choose the appropriate PPE to eliminate or reduce those hazards.
Safety
• Always keep the record of assigned tasks, incidents outcome and the person
incharge of the site and people who are working at site.
• Always have Layout/Route map of the Solar Power Plant
11. RULES OF ELECTRICITY
Electricity travels in a completed circuit path
Electricity always travels in the path of low
resistance
Electricity tries to travel in shortest path
Electricity always tries to travel to ground
12. ELECTRICITY AND PEOPLE
A person usually offers a lesser resistance path for
the electricity
The person forms a completed circuit when
touching the Ground and Electricity
The person forms a shortest path when touching
the Electricity

protect the lower legs and feet, and may be
used in combination with toe guards when
greater protection is needed.
• Safety shoes have impact-resistant toes and
heat-resistant soles that protect the feet
against hot work surfaces common in roofing,
paving and hot metal industries. The metal
insoles of some safety shoes protect against
puncture wounds. Safety shoes may also be
designed to be electrically conductive to
