The figure shows a network of currents. The magnitude of currents is shown in the figure. The current $I$ will be ........... $A$.

Consider the circuit shown. If all the cells have negligible internal resistance, what will be the current through the $2 \Omega$ resistor when steady state is reached (in $A$)?

In the circuit shown,the currents (in $A$) through the $50\; V$ and $30\; V$ batteries are,respectively:

In the given circuit,current $I$ is independent of the resistance $R_6$. Then

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

Refer to the circuit diagram given below. The heat generated across the $6\text{ }\Omega$ resistance in $100\text{ s}$ is $\frac{\alpha}{100}\text{ J}$. The value of $\alpha$ is . . . . . . . (Nearest integer)
