When a parallel plate capacitor is connected to a source of constant potential difference

Options

A. all the charge drawn from source is stored in the capacitor
B. the potential difference across capacitor grows very rapidly initially and this rate decreases to zero eventually
C. only half of the energy drawn from the source is dissipated outside the capacitor
D. all of these

Answer

D

Explanation

Initially when potential difference is high, hence rate of flow of charge is high. But when potential difference across capacitor reaches the applied potential difference, this rate tends towards zero. Energy drawn from source = QV, but energy stored in capacitor = `QV//2`
