- 1Alternating Current (AC)a flow of electric current that keeps changing direction at a very fast rate
- 2Direct Current (DC)an electric current that flows in one direction only. It is the form in which batteries supply electricity.
- 3Current- a flow of electricity
- measured in Amps (A)
- charge= charge passing/ time taken
- I=Q/t
( to remember equation think: I quit) - 4Energya form of power
- 5Voltage (V)- energy given/ carries per unit charge
- measured in volts (V) - 6Resistance- a measure of how difficult it is for charge to flow.
- measured in Ohms (Ω)
- in equations it has the symbol R - 7Power- the rate of transfer energy
- rate means per second
- measured in Watts - 8Energya form of power such as electricity, heat, or light that is used for making things work.
- 9static electricityelectricity that does not flow in a current but is found in some objects when they rub together & give an electric shock
- 10Voltmetera piece of equipment used for measuring voltage
- 11Ammeter-( not Amita) ]
