A capacitor and a resistor are connected in series with each other and in series with an accumulator of negligible internal resistance. The potential across the terminals of the capacitor is
twice the e.m.f of the accumulator
less than the e.m.f by the potential drop across the resistor
zero
the same as the e.m.f.
greater than
Correct answer is E
