In the circuit shown,what is the potential difference $V_{PQ}$?

The given figure shows a network of resistances and two batteries. Which of the two batteries is getting charged?

The currents in different parts of the electric circuit are shown in the following figure. The value of current $i$ is (in $\text{ A}$)

Five equal resistances are connected in a network as shown in the figure. The net resistance between the points $A$ and $B$ is

In a typical Wheatstone network,the resistances in cyclic order are $A = 10 \,\Omega $,$B = 5 \,\Omega $,$C = 4 \,\Omega $ and $D = 4 \,\Omega $. What should be done for the bridge to be balanced?

$A$ $6 \, V$ cell with $0.5 \, \Omega$ internal resistance, a $10 \, V$ cell with $1 \, \Omega$ internal resistance, and a $12 \, \Omega$ external resistance are connected in parallel. The current (in ampere) through the $10 \, V$ cell is
