Last week we completed our look at mains electricity with calculations of:
Electrical power (Watts, W) = potential difference (Volts, V) x current (Amps, A)
and:
Energy transferred (or work done) (Joules, J) = potential difference (Volts, V) x charge transferred (Coulombs, C)
Aim to answer and mark the following questions and bring your marked work to our lesson on Friday 27th January.
