The capacitor in Figure P19.70 is initially uncharged, and both switches are open. What is the current through the battery the instant after switch S₁ is closed?

 

In the circuits in Figures P19.67, P19.70, and P19.72, assume the resistance values are R₁ = 1500Ω and R₂ = 2400 Ω, and with capacitances C₁ = 45 μF and C₂ = 25 μF. The emf is ε = 5.5 V. The switches are labeled S.
