Consider the circuit of Figure 6.19. The AC supply has a peak voltage of 10 V and a frequency of 1 kHz. The resistor has a value of 1 k2, and the capacitor has a capacitance of 0.1 F.

a. find the Thevenin equivalent circuit

b. If we varied the frequency of the source, at what frequency would the impedence be:

i. Maximum

ii. Minimum

iii. What are the impedences for cases 9(b)i and 9(b)ii ?

c. Now we connect a resistor R in series with a 0.22 microFarad capacitor as a load connected to points A and B.

i. What value of Resistor R will not load the circuit when the frequency is 1 kHz?

ii. What value of resistor R will not load the circuit regardless of the frequency?
