Experiment 13 Charging and Discharging Capacitors 1. Introduction In this experiment you will measure the rates at which capacitors in series with resistors can be charged and discharged. The time constant RC will be found. Charging a capacitor. Consider the series circuit shown in Fig. 1. Let us assume that the capacitor is initially uncharged. When the switch S is open there is of course no current. If the switch is closed at t=0‚ charges begin to flow and an ammeter will be able

1. A 1.4M Hz carrier is modulated by a music signal that has a frequency components from 20 Hz to 10k Hz. Determine the range of frequencies generated for the upper and lower sidebands. Solution: Upper Side Band = 1‚ 400‚ 000 Hz + 20 Hz = 1‚400‚ 020 Hz Up to = 1‚ 400‚ 000 Hz + 10‚ 000 Hz = 1‚ 410‚ 000 Hz Lower Side Band = 1‚ 400‚ 000 Hz – 10‚ 000 Hz = 1‚ 390‚ 000 Hz Up to = 1‚ 400‚ 000 Hz – 20 Hz = 1‚ 399‚ 980 Hz 2.
