| Question | Answer |
| Alternating Current (AC) | a flow of electric current that keeps changing direction at a very fast rate |
| Direct Current (DC) | an electric current that flows in one direction only. It is the form in which batteries supply electricity. |
| Current | - a flow of electricity - measured in Amps (A) - charge= charge passing/ time taken - I=Q/t ( to remember equation think: I quit) |
| Energy | a form of power |
| Voltage (V) | - energy given/ carries per unit charge - measured in volts (V) |
| Resistance | - a measure of how difficult it is for charge to flow. - measured in Ohms (Ω) - in equations it has the symbol R |
| Power | - the rate of transfer energy - rate means per second - measured in Watts |
| Energy | a form of power such as electricity, heat, or light that is used for making things work. |
| static electricity | electricity that does not flow in a current but is found in some objects when they rub together & give an electric shock |
| Voltmeter | a piece of equipment used for measuring voltage |
| Ammeter | -( not Amita) ] Measures the flow of current |
