Visual charge/discharge of a capacitor through a load.

5F30.12 • D+0+12

diagram for demo

Visual charge/discharge of a capacitor through a load. The capacitors in the capacitor bank are in parallel. Closing or opening the capacitor switches selects a desired capacitance. Throw the large knife switch to the 'charge' position to charge the capacitors. Select a resistor value on the resistor box, then throw the knife switch to the 'discharge' position to discharge the capacitors through the resistance. The high impedance voltmeter shows both the exponential charging and discharging of the capacitors. NOTE: Short the capacitors before puttting away. CAPACITANCE
