Capacitance

The video tutorial explains how capacitors store electric potential energy in an electric field, using a camera flash as an example. It defines capacitance, discusses the work needed to separate charges, and explains the units and symbols used. A demonstration with a disposable camera shows how a capacitor is charged and discharged, converting stored energy into light and heat. Safety precautions are emphasized during the demonstration.

Describe the process of charging a capacitor using a battery.

What happens when a metal object is placed across the terminals of a charged capacitor?

Discuss the safety precautions one should take when working with capacitors.
