1- An RL circuit consists of a 27.5 resistor and a 330 mH inductor.

Part (a)Find its impedance Z at 25 Hz in .

Part (b)Find its impedance Z at 8 kHz in .

2- A series LC circuit consists of a 2.25 mH inductor and a 4.5 F capacitor.

Part (a)Find its impedance Z at 65 Hz in ohms.

Part (b)Find its impedance Z at 11 kHz in ohms.

3- To receive AM radio, you want an RLC circuit that can be made to resonate at any frequency between 500 and 1650 kHz. This is accomplished with a fixed 1.00 H inductor connected to a variable capacitor.

Part (a)What would be the minimum capacitance, in nanofarads, that would be required?

Part (b)What would be the maximum capacitance, in nanofarads, that would be required?
