Electricity by 2E2 Siti Azwani

Electricity
i) I have learnt that electricity is a controllable and convenient form of energy used in everyday life. Electricity is the flow of electrons. Without it, we may not be able to perform our everyday routine. Mainly, we used electricity for work, play, in the house and at work, (and at school).

ii) Electricity is a basic part of nature and it is one of our most widely used forms of energy. We get electricity, which is a secondary energy source, from the conversion of other sources of energy, like coal, natural gas, oil, nuclear power and other natural sources, which are called primary sources.

In every electricity, there will always be an electric current. An electric current is a flow of electric charge around a circuit. The charge is already in the wires. This charge is evenly spread out through the wires. As soon as you close the switch, the cell starts to push on the charge. So all the charge starts moving at once. An electric cell gives energy to the electrons and pushes them around a circuit.

Voltage is a measure of how much energy the electrons receive.
