Two wires of the same material are connected in parallel to a circuit. If the ratio of their lengths is $4/3$ and the ratio of their radii is $2/3$,then the ratio of the electric current flowing through the wires will be .......

When subjected to a voltage of $10 \, V$, the current through a resistor at a temperature of $40^{\circ} C$ is $0.1 \, A$. The temperature coefficient of resistance of the material of the resistor is $2 \times 10^{-4} {}^{\circ} C^{-1}$. The temperature of the resistor in ${}^{\circ} C$ when the current drops to $0.098 \, A$ is

When electric bulbs of same power,but different marked voltage are connected in series across the power line,their brightness will be:

Consider the four circuits shown in the figure given below. In which circuit is the power dissipated the greatest? (Neglect the internal resistance of the power supply)

When a resistor of $11 \Omega$ is connected in series with an electric cell,the current flowing in it is $0.5 \ A$. Instead,when a resistor of $5 \Omega$ is connected to the same electric cell in series,the current increases by $0.4 \ A$. The internal resistance of the cell is (in $\Omega$)

The equivalent resistance between the points $P$ and $Q$ of the circuit given is
