Static electricity refers to the buildup of electric charge on the surface of objects and can be contrasted with current electricity which is delivered through wires. There are 5 types of electric discharge that can occur. Static electricity can be dangerous in places like operating theaters, around computers, and when refueling if flammable vapors are present as sparks from static discharges can ignite them. Current is the flow of electric charge through a medium like a wire and is measured in amperes. Potential difference refers to the difference in electric potential between two points in an electric field and is measured in volts. Capacitors are electrical components that store energy in an electric field and are measured in farads.

An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in a plasma.

WHY ELECRICITY IS IMPORTANT ?
Electricity is an essential part of modern life. People use electricity for lighting, heating, cooling, and refrigeration and for operating appliances, computers, electronics, machinery, and public transportation systems.
Electrical energy is one of the most commonly used forms of energy in the world. It can be easily converted into any other energy form and can be safely and efficiently transported over long distances. As a result, it is used in our daily lives more than any other energy source.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2. Static electricity
Refers to the build-up of electric charge on the
surface of the objects.
It can be contrasted with current,electricity which
can be delivered through wires as a power
source.
There are 5 types of electric discharge (
Spark,Brush discharge,propagating brush
discharge,cone discharge and corona
discharged)
3. Lighting
Refuelling
Sparks from statics electricity can be dangerous when flammable vapour is present.
Operating Theaters
Dust and germs attracted by charged objects.We need to ‘earthed’ all the
equipment.
Computers
Computers require simillar ‘anti-static’ conditions as they are vulnerable to
electrostatic damage.
5. Electric Current
→ is a flow of electric charge through a medium.
→ Charge typically carried by moving electrons such as
wire.
→ The SI unit is AMPERE.
→ Is measured using AMMETER.
7. Series
current is the same at all the points in a series
circuits.
Parallel
The sum of the current in the branches of a
parallel circuit equals the current entering
or leaving the parallel section.
Series and Parallel circuits
8. Potential Difference
* The difference in electric potential between two
pointsin an electric field.
* measured in volts
* The work that has to be done in transferring unit
positive change from one point to the other.
9. Resistance
The opposition of a conductor to current called
RESISTANCE.
The formulae R=V/I
the smaller the I is for a given V,the greater R.
The ohm is the resistance of a conductor.
10. Ohm’s Law
Metallic Conductor (current through a metallic
conductors is directly propotional to the
voltage)(there are called ohmic or linear conductors)
Semiconductors diode
Filament Lamp
Variation of resistance with temperature
Variation of resistance with light intensity
11. In series same current flows through
each and total voltage.
In parallel the voltage between the
ends of each is the same.
12. Is a passive two terminals electrical
component used to store energy in electric
field.
its measured by farads(F)
Smaller units such as the microfarad are
more convenient.
A capasitors store electric charge and its
useful in many electric circuits
14. Charging
It can be charged by connecting a battery across
it.During the charging,there is brief flow of lectrons
round the circuits.A momentary current would be
detected by a sensitive ammeter.
Discharging
When a conductor is connected across a charged
capasitors,there is a brief flow of electron from the
negatively charged plate to the positively one.
15. Electric Power
Is the rate at which electric energy is transferred by
an electric circuits
The SI of power is watt
16. Filament lamps
Is a small coiled coil of tungsten wire,which
become white hot when current flows throught
it.Its contain nitrogen and argon,not air.
Fluorescent strips
Transfer only 10% of the electrical energy supplied
to light; 90% becomes heat.
Compact Fluorescent lamps
Last up to 8 times longer.used about 5 less energy
than others.
Electric lighting
17. Heating elements
Three-heat switch
Fuses
Electric heating
18. Circuits in parallel
Switches and fuses
Staircase circuits
Ring main circuits
Fused plug
Earthing and safety
Circuits breakers
Double insulation
19. Danger of electricity
Electric shock
electric shocks occurs if current flows from an
electric circuit through a person body’s to earth.Its
causes by damaged insulation or faulty wiring.
Fire risks
20. How to AVOID!!
1. Switch off the electrical supply to an appliance
before starting repairs.
2. Use plugs that have earth pin.
3. Do NOT allow appliances or cables to come into
contact with water.
4. Do NOT have long cables trailing across
room,under carpet or in other conditions.
5. Use plugs that have the correct fuse
6. Do NOT attach to many appliances to a circuit
7. Dont overload circuits by using to many adapters
