When an alternating voltage is applied to a purely resistive circuit the A voltage lags the current B the voltage leads the current Ccurrent leads the voltage Dcurrent is in phase with the voltage?

'A' and 'C' are saying exactly the same thing.

The correct choice is 'D'.

The complex impedance of a purely resistive circuit is purely real.

Since there is no reactance, there is no phase shift, so the power

factor is ' 1 ', KVA = KW, KVAR = 0, etc.
