What is meant by charge?
(b)
A heater uses a wire with resistance $18.0\,\Omega$ and is connected to a $240\,\text{V}$ supply. It is turned on for $2.60\,\text{Ms}$. Calculate:
(b(i))[2]
the heater's power transformed.
(b(ii))[1]
the current flowing in the heater.
(b(iii))[2]
the charge that passes through the heater in this time.
(b(iv))[2]
the number of electrons each second passing a fixed point in the heater.
