A bolt of lightning is electricity travelling from the clouds to the ground, or from cloud to cloud. Some methods of generating electricity, like burning gas and coal, create greenhouse gases that cause climate change.
People are trying to make more of our electricity in ways that are good for the environment , like using wind power or solar power. Wind power generates electricity by using the wind to turn the big arms on a wind turbine. Solar power generates electricity by absorbing the heat and light from the sun in special panels.
Electricity has led to a lot of changes in our lives. Before electricity, if you wanted to light your house at night, you had to use candles, or lamps filled with oil or paraffin. In , the first electric streetlights in the world were put in London. In , Godalming in Surrey became the first town in the world to have an electricity supply that everybody in the town could use.
Lots of trains are powered by electricity. They either get it from a wire that runs over the tracks, or from a third rail. One of the reasons electricity changed our lives so much is that it can make things much more convenient. Before electric street lights, it was the job of some people to go around lighting the gas-powered lamps that towns used to have on their streets; they were called lamp lighters. Even though you can get small wind turbines to use at home, wind turbines have to be very big in order to make a lot of electricity.
Each blade on a big wind turbine could be as long as four double-decker buses! The best place to put a wind turbine is somewhere where there is a lot of wind to turn it. The more wind there is, the more electricity you can make. The best places often high up on a hill or on top of a tall building, but it can also be good to build wind turbines out at sea.

There is a specific way of the flow of electrons and this flow of energy is explained with current electricity assignment help. Current electricity homework help is for students who find it a little difficult to understand the different terms of electric current.
It is very important for you to know how current is measured. The SI unit of current is ampere A. There are many different ways of measuring current but there is one most commonly used method that is to perform an indirect measurement where the voltage is measured across a precision register and then using the law of Ohm to measure the current across the resistor. In this chapter on current electricity, we have provided current electricity assignment help for all those finding this term a little difficult to understand.

Two types of current Current electricity assignment help provides a brief description of the two types of currents that are in widespread use today. Direct current — Here the electrons present flow in one fixed direction. One example of this type of current flow occurs in batteries where electrons flow from the negative side to the positive side Alternating current —Here the electrons are pushed back and forth, continuously changing the direction of the flow.
Big power plants use generators that produce alternating current. For this reason, they should take Electricity Homework Help guidance.

This is a kind of electromagnetic field created by electric charge. This is a movement of particles that are charged electrically. This is a property of subatomic particles that help to determine electromagnetic interactions.
This is the ability of electric field for doing work on electric charge.
We normally get electricity from the mains or batteries. A circuit is a complete route or course. An electrical circuit has electricity flowing throught it. Electricity only flows when the circuit is complete with no gaps.
What are electricity and power generation? Electricity is a type of energy that we use to power lots of things around our homes. It is used to power lights, mobile phones, TVs, radios, and even the computer that you are reading this on. To use all this electricity, we have to make it – this is called generation.
