Vedclass · Answer

(D) The total resistance of the circuit is $R_{total} = 100 \, \Omega + 100 \, \Omega + 80 \, \Omega + 20 \, \Omega = 300 \, \Omega$.The current flowing through the circuit is $I = \frac{V}{R_{total}} = \frac{48 \, V}{300 \, \Omega} = 0.16 \, A$.The potential difference across $PQ$ (which corresponds to the $20 \, \Omega$ resistor) is $V_{PQ} = I 	imes R = 0.16 \, A 	imes 20 \, \Omega = 3.2 \, V$.

In the given electric circuit, the potential difference across $PQ$ is approximately ...... volts.
