I came across a question in my Physics Paper
"What is the work done by a battery in charging a capacitor" (Assume circuit has no resistance).
This is what i thought...
The Energy in the field between the capacitor plates is 0.5CV^2 where C=capacitance and
V=Battery EMF.So the ans should be 0.5CV^2.
BUT the actual solution in paper was...
Net Work done=Net Charge * Voltage
W=QV
W=CV^2 .
What is the correct ans?
