CALC Consider the circuit shown in Fig. P30.63. Let = 36.0 V, R₀ = 50.0 Ω, R = 150 Ω, and L = 4.00 H. (a) Switch S₁ is closed and switch S₂ is left open. Just after S₁ is closed, what are the current i₀ through R₀ and the potential differences v_ac and v_cb? (b) After S₁ has been closed a long time (S₂ is still open) so that the current has reached its final, steady value, what are i₀, v_ac, and v_cb? (c) Find the expressions for i₀, v_ac, and v_cb as functions of the time t since S₁ was closed. Your results should agree with part (a) when t = 0 and with part (b) when Graph i₀, v_ac, and v_cb versus time.
