PHYS345 Electricity and Electronics

Answers for 9/23 Assignment

Answer for 4.35

The resonant frequency will be that for which R2 = XL(XC - XL).

For the circuit parameters stated, this will be satisfied when f = 78 kHz.

Answer for 4.37

22 mA \/ 0 deg.

Answer for 4.48

VTH = 10 V at the appropriate frequency for both a) and b).

a). ZTH = (500 + j10) ohm, slightly inductive.

b). ZTH = (500 - j10) ohm, slightly capacitive.

Answer for 6.7

The resonant frequency is 4.9 rad/sec.
