Episode 128: Energy Stored by a Capacitor

Comments (0)

Produced by the Institute of Physics, this learning episode looks at the energy stored in a capacitor. Students undertake a practical investigation to look at the energy stored and how this varies with potential difference and capacitance.

The activities include:
• energy transfer - using a capacitor and an electric motor
• using capacitors to light bulbs and compare the energy stored with the voltage applied
• calculating stored energy
• measuring stored energy
• student questions, solutions provided
