Two light bulbs shown in the circuit have ratings $A(24 \mathrm{V},24 \mathrm{W})$ and $B(24 \mathrm{V}, 36 \mathrm{W})$ as shown. When the switch is closed.

A series circuit consists of two capacitors, a resistor and an ideal voltage source. The circuit is initially at steady state. Now a conducting wire is shorted across the capacitor $C$ as shown by dotted line. After shorting the wire, select the correct statement/statements.

$AB$ is part of a circuit as shown that absorbs energy at a rate of $50 \mathrm{W}$. $E$ is an emf device that has no internal resistance.

If in the circuit shown in the figure, power dissipation is $150 \mathrm{W}$, then find the value of $R$ (in $\mathrm{\Omega }$).

Two circular rings of identical radii and resistance of $36 \mathrm{\Omega }$ each are placed in such a way that they cross each other’s centre $C_1$ and $C_2$ as shown in the figure. Conducting joints are made at intersection points $A$ and $B$ of the rings. An ideal cell of emf $20 \mathrm{V}$ is connected across $A$ and $B$. Find the power delivered by the cell (in ${10}^2 \mathrm{W}$).
