In figure, capacitor C is charged to V₀ = 50 V with upper plate positive. Switch S is closed at t = 0. Current through the circuit at t = 0 and final voltage across C are respectively—

1. 15 A, 200 V
2. 20 A, 200 V
3. 25 A, 250 V
4. 15 A, 150 V

Correct Option: A

The given circuit
at t = 0 the equivalent circuit becomes

I =	(200 – 50) V	= 15 A
	10Ω

And, the final voltage across C means at steady state capacitors becomes open circuited as shown below:
V_C(∞) = 200V
Hence alternative (A) is the correct choice.
