A resistor carries a current $I$. The potential difference (p.d.) across it is $V$. What other physical quantity is required in order to determine the energy transferred $W$ by the resistor?
- Athe electromotive force (e.m.f.) $E$ of the source
- Bthe power $P$ dissipated
- Cthe resistance $R$ of the resistor
- Dthe time $t$ for which there is a current in the resistor
