Question

The energy stored in the capacitor in the steady state is (A) 338 μ J (B) 196 μ J (C) 98 μ J (D) 8 μ J

Tardigrade Admin · Accepted Answer

At steady state, capacitor acts as open circuit.

V_{A} + 3 \times 1 - 14 - 5 \times 3 = V_{B}

\Rightarrow V_{A} - V_{B} = 26 V

Energy stored in capacitor,

U = \frac{1}{2} C V^{2} = \frac{1}{2} \times 1 0^{- 6} \times (26)^{2} = 338 μ J
