5F30.10 Capacitor and Lightbulb
A 110,000 microF capacitor, a light bulb, and a 24 V dc supply in series show a long time constant where the bulb dims as the capacitance charges. Double the capacitance to show the effect of an ever longer time constant.
Location: Capacitors and switch on foam board F3-5; Lightbulb: D1-2; Power Supply: Q1-5; Oscilloscope: K2-4
