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)
