Energy input for Parallel Plate Capacitors

[dave_western]

I'm supposed to show that while a capacitor is being charged, the energy flows into the region between the plates at the same rate as the electrostatic energy in the capacitor increases. I'm not sure exactly what is being asked of me... are there formulae for these?

I feel stupid.
