In these activities, from the Institute of Physics, the concept of electrical power is explored. Students find that the energy transferred by an electrical component depends on the potential difference, current and the time for which it operates.

From the Institute of Physics, this learning episode links Kirchhoff’s circuit laws to the conservation of charge and energy. Students can verify the laws experimentally and use them to solve simple circuit problems.
