Discharging a Capacitor

The video tutorial demonstrates the basic concept of charging and discharging a capacitor using a disposable camera. Initially, the capacitor is fully discharged. The instructor connects a battery to charge the capacitor, explaining the conversion of chemical energy to electric potential energy. Once charged, the capacitor is discharged by placing a metal paperclip across its terminals, creating a spark. The demonstration highlights the electric potential difference and energy storage in capacitors.

What is the initial state of the capacitor in the disposable camera?

• Fully charged with a strong electric field

• Partially charged with a weak electric field

• Partially discharged with a moderate electric field

• Fully discharged with no electric field

What happens when the battery is connected to the capacitor?

• The battery moves charges between the plates of the capacitor

• The battery loses all its energy

• The capacitor discharges completely

• The capacitor remains unchanged

What type of energy is stored in the capacitor once it is charged?

• Kinetic energy

• Thermal energy

• Mechanical energy

• Electric potential energy

What is used to discharge the capacitor in the demonstration?

• A metal paperclip

• A plastic rod

• A rubber band

• A wooden stick

What is observed when the capacitor is discharged using the metal paperclip?

• A loud explosion

• A bright flash of light

• A spark is created

• No visible effect
