d At steady state current will not flow in branch that contains capacitator, so $6 \Omega$ and $2 \Omega$ will become in series so net current $\left(\frac{12}{6+2}\right)$ Resistor of $4 \Omega$ will become short circuited $I_{n e t}=\frac{3}{2} A$
Voltage across capacitor = Voltage across $6 \Omega$ $\frac{q}{C}=i R$
$\frac{q}{2 \times 10^{-6}}=\frac{3}{2} \times 6$
$q=18 \times 10^{-6}$
$q=18 \mu C$

A $100\, W \, bulb\, B_1$ and two $60\, W \,bulbs \,B_2$ and $B_3$, are connected to a $220\, V$ source, as shown in Figure. Now $P_1, P_2$ and $P_3$ are the output powers of the bulbs $B_1, B_2$ and $B_3$ respectively. Then
Two wires of same material have length $L$ and $2L $ and cross-sectional areas $4A$ and $A$ respectively. The ratio of their specific resistance would be
A cell sends a current through a resistance $R$ for time $t$. Now the same cell sends current through another resistance $r$ for the same time. If same amount of heat is developed in both the resistance, then the internal resistance of cell is
At what rate the potential difference between the plates of a capacitor be changed to set up a displacement current of $1\, A$ in a capacitor of $2\,\mu F$ ?
A generator has armature resistance of $0 .1\,\Omega $ and develops an induced emf of $120 \,V$ when driven at its rated speed. Its terminal voltage when a current of $50\,A$ is being drawn is ................. $V$
