Question 1:
a) Plot and determine the voltage vo (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)

b) In the circuit of Figure 2, determine the following:
Total impedance, ZT (In Multisim, by using impedancemeter and without impedancemeter)
Voltage, Vab(Use multisim)
Verify the results in part (i) & part (ii) by calculation.
