A $1\ µF$ capacitor is connected in the circuit shown below. The
e.m.f. of the cell is 3 volts and internalresistance is 0.5 ohms. The
resistors R_1and R_2have values 4 ohms and 1 ohm respectively.
Thecharge (in $µC)$ on the capacitor in steady state must be

Show answer and solution

In steady state no current flows through capacitor. The
potential difference across capacitor andresistor of resistance R_2is
same.

\mathbf{\therefore}

charge on capacitor

= CV = C \times 3 = 1\mu F \times 3 = 3\mu C
