Solution
The correct options are
A VA
C W
We know, Electric power = VI, where V is the potential difference across the conductor and I is the current through the conductor.
The S.I unit of voltage is volt and S.I unit of current is ampere. So the S.I unit of electric power is volt-ampere(VA) or watt(W).
