$A$ battery of $6 \text{ V}$ is connected to the ends of a uniform wire $3 \text{ m}$ long and of resistance $100 \Omega$. The potential difference between two points $50 \text{ cm}$ apart on the wire is: (in $\text{ V}$)

Refer to the figure given below, current between terminals $A$ and $B$ is . . . . . . $A$.

$A$ simple circuit contains an ideal battery and a resistance $R$. If a second resistor is placed in parallel with the first,which of the following statements is correct?

To verify Ohm's law,a student connects the voltmeter across the battery as shown in the figure. The measured voltage is plotted as a function of the current,and the following graph is obtained. If $V_0$ is almost zero,identify the correct statement.

The current $i$ in the circuit shown in the figure is

In the figure shown,the capacity of the capacitor $C$ is $2\,\mu F$. The current in the $2\,\Omega$ resistor is ............... $A$.
