| Question | Answer |
| Ohms Law | Volts = Current x Resistance V = I x R | The Unit of energy | 1 Watt = 1 Joule/1 second | Electrical Power | The unit for power is watts P= V I Or P=I² R or P=V²/R | Resistors in series | R total = R1 + R2 …… + R n & V total = V1 + V2 | Resistivity | R =ρ x L /a |
