Question 1:

a) Plot and determine the voltage v_o (t) for t > 0 for the circuit in Figure 1. Also estimate the time it takes to dissipate 50 percent of capacitors voltage to 4 kΩ resistor.

(Note: show all the necessary steps of multisim to support your answers)

Figure 1

b) In the circuit of Figure 2, determine the following:

Total impedance, Z_T (In Multisim, by using impedancemeter and without impedancemeter)

Voltage, V_ab(Use multisim)

Verify the results in part (i) & part (ii) by calculation.

Question 2:

a) For the circuit in Figure 3, obtain the average power, complex power and power factor delivered to 10 kΩ resistor. (Use Multisim)
