CIRCUIT THEORY

REVIEW QUESTIONS.

1. At what frequency is a circuit consisting of a 40-pF capacitor and a 0.09 mH coil with a Q of 80 series resonant?

2. What is the bandwidth of the circuit in question 1?

3. If the circuit of question 1 is connected to a 0.5 mV source, what voltage will appear across the capacitor at resonance?

4. What current will flow through the circuit at resonance?

5. What value of capacitance is required to tune a 0.5-mH coil to series resonance at 465 kHz?

6. What value of inductance in series with a 12-pF capacitor is resonant at 45 MHz?

7. A tuned circuit consisting of 0.04-mH inductance and 100-pF capacitance in series has a bandwidth of 25kHz. What is its Q?

8. What is the resistance of the coli in the tuned circuit of question 7?

9. What is the resonant frequency of a tuned circuit consisting of the coil and capacitor of question 1 connected in parallel?

10. What is the impedance of the parallel tuned circuit of question 9 at resonance?
