Question

A capacitor is connected to a cell of emf $E$ and some internal resistance $r$. The potential difference across the capacitor when it is fully charged is:

• A. cell is $E$
• B. cell is $<E$
• C. Capacitor is $<E$
• D. Capacitor is $>E$

Answer 1

The correct option is A cell is $E$

When a capacitor is fully charged, then the current is drawn by it. When no current flows the circuit, potential difference across the cells emf of cell$=$ potential difference across the capacitor.
