For the circuit shown in Figure 3: + V1 H 9V S1 B R1 1ΚΩ C1 470μF Figure 3: Circuit diagram for question 4 The circuit in Figure 3 shows the circuit set up to charge and discharge a capacitor. b) Draw the detailed current waveform through the circuit and voltage waveform across capacitor for the Capacitor charge cycle when the switch is at position A. (Consider the initial capacitor voltage to be OV).

C2 The next two questions refer to the following figure. The switch is initially open and both capacitors are initially uncharged. All resistors have the same value R, and both capacitors have the same value C. R2 R3 bat R1 ww (f) 1 pt. Immediately after the switch is closed, which resistor has the most current through it? (i) R1 (ii) R2 (iii) R3 (iv) Rị and R2 (v) R2 and R3 (vi) All have the same current (g) 1 pt. A long time after the switch is closed, which resistor has the most current through it? (i) R1 (ii) R2 (iii) R3 (iv) R1 and R2 (v) R2 and R3 (vi) None have current

a) With switch J2 open, close switch J1. Estimate the time it takes to do it. Obtain the equations for the voltage and current of the capacitor. Determine the energy stored by the capacitor. b) Open switch J1, close switch J2. Estimate the time it takes to do it. Obtain the equations for the voltage and current of the capacitor.
