Electric Power

Describe the transfer of energy into, out of, or within an electric circuit, in terms of power.

  • The rate at which energy is transferred, converted, or dissipated by a circuit element depends on the current in the element and the electric potential difference across it. Relevant equation:
  • Derived equations:
  • The brightness of a bulb increases with power, so power can be used to qualitatively predict the brightness of bulbs in a circuit.
