In this presentation i have explained the overview of power system that what it contains and how does it works and how power is generated from various sources of energy.
A presentation done for part of my A-level studies, and also for my personal interest too.

Most microfilm produced prior to 1980 has a base made of cellulose acetate, which is subject to a special kind of degradation known as the “vinegar syndrome.” As microfilm ages and begins to deteriorate, which is especially affected by heat and humidity, acetic acid is released, further speeding up the deterioration process and resulting in a vinegary smell. As the syndrome develops, microfilm will distort, become brittle, and eventually become unusable as it separates between the emulsion and base layers. The vinegar syndrome is a looming and serious threat to practically all large microfilm collections. This program will provide information on how and why the vinegar syndrome develops in a microfilm collection, how one can test for the syndrome, and what options or solutions are available. The program will also highlight the problems confronting UNC Greensboro, as it deals with an outbreak of vinegar syndrome discovered in September 2010.

I. Introduction to Electricity
Definition of Electricity: Electricity is a form of energy that results from the movement of charged particles, such as electrons. It is an essential part of our daily lives and has numerous applications in various fields.
Sources of Electrical Energy: Electrical energy can be generated from a variety of sources, including coal, natural gas, nuclear power, and renewable sources such as solar and wind power.
Electrical Circuit: An electrical circuit is a closed loop through which electric current flows. It comprises of a source of electrical energy, conductors, and electrical devices such as lamps and motors.
II. Electrical Energy
Electrical Potential Difference: Electrical potential difference, also known as voltage, is the energy per unit charge that is required to move a charge from one point to another in an electrical circuit.
Electric Current: Electric current is the flow of electric charge through a conductor. It is measured in Amperes (A) and is the rate at which electric charge flows through a circuit.
Resistance: Resistance is the property of a material to oppose the flow of electric current. It is measured in Ohms (Ω) and is an important parameter in electrical circuits as it affects the amount of current flowing through the circuit.
III. Electrical Circuits
Series Circuits: In a series circuit, the components are connected in a single loop so that the current flows through each component in turn. The total resistance of a series circuit is equal to the sum of the resistances of the individual components.
Parallel Circuits: In a parallel circuit, the components are connected in such a way that each component has its own separate path for the current to flow through. The total resistance of a parallel circuit is equal to the reciprocal of the sum of the reciprocals of the individual resistances.
Combination Circuits: Combination circuits are a combination of series and parallel circuits, and they provide a more complex electrical circuit.
