Assignment

1. One circuit uses a 1 µF capacitor and 10 µH inductance connected in series. If the frequency of the applied power source is 110 Hz, what will be the total impedance offered by this L and C?
2. Construct a series LC circuit with a 1 µF capacitor, 1 H inductor, and an AC power source of 50 V. Vary the power source frequency from 10 Hz to 200 Hz in intervals of 10 Hz and plot the graph of frequency vs current through the circuit.
3. In a series LC circuit, if the two terminals of the capacitor are shorted, what will be the effect on the total current through the circuit and the voltage drop across the capacitor and inductor?
4. A radio can tune over the frequency range of a portion of the MW broadcast band (800 kHz to 1200 kHz). If its LC circuit has an effective inductance of 200 µH, what must be the range of its variable capacitor?
5. A radio transmitter transmits a signal of 1 MHz. Discuss five possible selections of capacitor and inductor values to capture this signal.
