The power in a resistive circuit is the product of the voltage, current and the cosine of the phase angle. Hence if either voltage or current is zero, the power is zero.

So,as we know current and voltage are indirectly proposed. Then when current is then voltage is max, when voltage is zero current is max. The current lonely can't because it is just electron and the emf is voltage.
similar voltage it can don't anything with current why means when there's nothing to move then what's the work of voltage there. so, the power for a purely resistive circuit is zero either current or voltage is zero.
