Increasing the charge on both particles by a factor of 2 while decreasing the distance by a factor of 2 will: Materials that make good electrical insulators contain atoms with: Page 2 Question 6 6.
An atom becomes a negative ion when: When given the current and resistance, power can be calculated by: In the diagram of an electric force field, the field lines represent: Adding a light bulb to a parallel circuit will: Generators are used to generate voltage in what type of power plant? Page 3 Question 11 Increasing the distance between particles by a factor of 2 while leaving all other factors the same will: When given the current and voltage, power can be calculated by: Resistance is equal to: Page 4 Question 16 Decreasing the charge on both particles by a factor of 2 while leaving all other factors the same will: If the voltage is increased: The two types of current are: The resistance of a wire increases if: Page 5 Question 21 Power is a measure of how much: The voltage lost in each light bulb in a series circuit: Page 6 Question 26 It takes a lot of work to generate electricity, and some of the ways we do have bad side effects on the environment.
Because Britain is north of the equator, the sun is always to the south of us in the sky. This means that in Britain it is best to put solar panels facing south, so that the sun shines on them for as much of the day as possible.
Electricity can also be a lot cleaner and nicer than the alternative. In , the London Underground started to use electric trains because it meant there was no dirty, smelly smoke from steam engines in the tunnels and stations.
All underground railways around the world soon did the same thing. Lots of electricity is generated by burning fuels that create greenhouse gases and contribute to global climate change. People are trying to reduce this by generating more energy by environmentally-friendly methods like wind or solar power.
Nuclear power stations often look similar to coal or gas power stations with lots of big cooling towers. Electricity can be very dangerous when it travels through you. It can seriously hurt or even kill people. Not all items that use electricity have to be plugged into mains sockets. Batteries can be used to store small amounts of electricity so that it can be used in small things that you can carry around like iPods and video game players.
Coal — coal is turned into electricity by burning it to make steam to turn a turbine; unfortunately, this makes carbon dioxide that causes global warming Cooling towers — these are used at power stations to get as much heat as possible out of steam that has been used to make electricity; this makes the power stations more efficient.
They are normally very wide towers, and sometimes look as though they have clouds coming out of them! It saves money, and helps the environment. Help find out how to power different electrical items , and how to be safe with electricity suitable for KS1. Try to create enough power from a solar panel and a wind turbine before the clock stops!

Visit an exciting new hydroelectric power station built inside a mountain in the Scottish Highlands. Learn more about hydropower at Rheidol power station in Wales.
Find out more about nuclear power at Wylfa power station in Wales. Like a river current is the flow of water molecules, electrical current is the flow of charged particles. Did you know that electrical current is affected by the voltage and resistance in a circuit? Electric circuits can be configured to power several loads, such as light bulbs, in series or in parallel. Power is a word we use all the time, but do you really know what it means?
