Explain how the current in the circuit depends on the resistance in the circuit
If the resistance increases the current decreases. A high resistance makes it harder for the current to flow.

Explain why a wire gets when a current flows through it
As the electrons flow through a lattice of ions they bump into them.

Compare AC and DC currents
They both transfer energy. AC is used on the national grid and DC is used in batteries. DC flows in one direction, whereas AC changes many times a minute.
3 of 6
Equation for charge
Charge = current x time
4 of 6
Equation for energy
energy = charge x potential difference OR energy = current x potential difference x time
5 of 6
Equation for resistance
resistance = voltage / current
