==Description==
A large 50 V capacitor is charged and discharged using a light bulb as a resistor.

==Equipment==
* Charging/Discharging capacitor setup
* Power supply

==Instructions==
* Make sure the switch is placed in the center position
* Set the power supply to 50V
* Connect the setup to the power supply
* Put the switch in the 'charge' position and watch the bulb light up
* (Optional) Disconnect the power supply (to show that in the discharge the light bulb is only powered by the capacitor)
* Put the switch in the 'discharge' position and watch the bulb light up
* Put the switch back in the center position and turn off the power supply.
