42 Capacitor/Bulb Demo A battery is connected through a push switch to a large capacitor with the return path through a lamp. When the switch closes the circuit current flows to charge the capacitor. The lamp lights brightly and then dims exponentially. Connecting the lamp directly across the capacitor it becomes the power source current flows to discharge the capacitor through the lamp which again initially glows brightly and then dims exponentially. 42
43 RC Circuit Driven with Square Wave Input Demo In this demo the power supply is periodically switched on and off. When it is on the capacitor charges and the voltage across it ramps up exponentially. When it off the capacitor discharges and the voltage ramps back down again exponentially. By adjusting the R and C values the time constant of exponential changes. 43
