This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to use the formula 𝐸 = 𝑄𝑉 to find the energy dissipated to the environment by the component of an electronic circuit.

Objectives

Students will be able to

use to determine the energy gained or lost, , by a charge moving across a potential difference ,
use to find the power of a circuit component given the current, , through it and the potential difference, , across it,
use .

Prerequisites

Students should already be familiar with

using to calculate the current, , through a circuit component given the charge, , that passes through it in time ,
Ohm’s law: ,
using to find the power, , of a circuit component given the amount of energy transferred by it, , in time ,
adding potential differences and resistances in series,
adding currents in parallel.
