Extracted text: 4 mA R 5 kn R2 10 µF vc I k. R3 3 kn In the circuit given above ; a) When the switch is in position 2 at t= 1 second, current (lc) and voltage (Vc) in the capacitor find the mathematical expression based on time. b) What is the capacitor current (Ic) and voltage (Vc) att = 2r seconds? c) If the switch is set to position 2 att= 21 , the voltage across the capacitor (Vc) , required for time-dependent change find the mathematical expression. d) Draw the time-dependent waveform of the voltage determined for the conditions in items a, b and c.
