Electricity in the home

State the UK Mains voltage supply

230 Volts

1 of 7

Explain the difference between AC and DC.

Direct current is straight but alternating current fluctuates.

2 of 7

Name the 3 wires in a plug and give their functions

The live wire- carries Potential difference from supply. The Neutral wire- Completes the circuit. The Earth wire- runs to the ground for safety.

3 of 7

Explain how someone can get an electric shock

The charge will flow through them and the voltage will follow, shocking their body.

4 of 7

Give the equation that links time, energy and power, including units

Energy transferred = Power (Watts) X Time (Seconds)

5 of 7

Give the equation that links pd, charge flow and energy, including units

Energy transferred =charge flow (Couloms) X Potential difference (Volts)

6 of 7

Give the equation that links power, current and resistance, including units

Power (Watts) = (Current)SQAURED X Resistance (Ohms)
