Question

The switch has been in position a for a long time when it is moved to position b at time t = 0. The values for the circuit are as follows:
I_a = 0.250A, R_a = 44.0Ω, R_b = 37.0Ω, R_c = 24.0Ω, R_d = 20.0Ω, R_e = 30.0Ω, V_e = 45.0V, C = 40.0μF.
Recall that for a capacitor, i=C·dv/dt. (Hint: source transformations might help as well.)

When the switch has been in position a for a long time, solve for the voltage across R_b, and the voltage across the capacitor.
Solve for the voltage across the capacitor immediately after the switch is moved to position b at t = 0, and explain why.
After the switch is moved to position b, solve for the time constant of the circuit.
Solve for the voltage across the capacitor v(t) as a function of time, when t ≥ 0.
