Question

The shown circuit has ε=10 V, C=1 μF, R₁=2 Ω, R₂=2 Ω and R₃=1 Ω. The capacitor is initially uncharged and switch S closes at t=0. Which statements are correct?

G1 Physics · Accepted Answer

At t=0⁺ the uncharged capacitor shorts R₃, so its current is zero. R₁ and R₂ are equal parallel branches and keep a constant current ratio. In steady state C is open and the resistive network gives 5 A through R₃; the final capacitor voltage is 5 V, so Qₘₐₓ=CV=5 μC. All statements are correct.
