In this lesson, we will learn how to use the formula E = QV to find the energy dissipated to the environment by the components of an electronic circuit.

Lesson Plan

Students will be able to

  • use 𝐸=𝑄𝑉 to determine the energy gained or lost, 𝐸, by a charge 𝑄 moving across a potential difference 𝑉,
  • use 𝑃=𝐼𝑉 to find the power of a circuit component given the current, 𝐼, through it and the potential difference, 𝑉, across it,
  • use 𝑃=𝐼𝑅.
