Please show work! Thank you!
In the circuit of the figure below, the switch S has been open for a long time. It is then suddenly closed. Take epsilon = 10.0 V, = T_1=59.0 kOmega, R_2= 115 kOmega, and C = 14.0 MewF Determine the time constant before the switch is closed. Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully, s Determine the time constant after the switch is closed. Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully, s Let the switch be closed at t = 0. Determine the current in the switch as a function of time. (Assume I is in A and t is in s. Do not enter units in your expression. Use the following as necessary: t.)Solution
Topen = R C = (59 + 115) * 103 * 14.0 * 10-6
= 2.44 s
------------------------------------------------
When the switch is closed, the capacitor discharges through 115 kohm resistor
Tclosed = 115 * 103 * 14.0 * 10-6 = 1.61 s
------------------------------------------------
I = Ib + Ic = [ delta Vb / R ] + [I0 e-t/Tclosed]
= [ 10 / 59 * 103 ] + [I0 e-t/1.61]
I0 = 10 / 115 * 103 = 86.9 muA
I = [ 10 / 59 * 103 ] + 86.9 e-t/1.61 muA
