The Main Idea

Measuring the power in a circuit can provide useful insight into the ability of a circuit to accomplish a given task. In order to understand how to calculate and interpret power in a simple circuit, one must know the mechanical definition and significance of Power. For this section, we will be using the unit of Watt for power.

It is important to note that the power in parts of a circuit can be represented in several different ways. Most commonly, power in a circuit is expressed in terms of Voltage (E, Emf, Volts), Current (I, Amps), and Resistance (R, Ohms).

A Mathematical Model

The power dissipated in a resistor is [math]\displaystyle{ P=IV }[/math] or [math]\displaystyle{ P=I^2R }[/math] or [math]\displaystyle{ P=V^2/R }[/math]
