Calculate Power given Electric Current and Resistance





Formula

The formula to calculate Power (P) is:

\[ P = I^2 \cdot R \]

Where:

Definition

Power is the rate at which electric energy is transferred or converted, typically measured in watts, and is a fundamental concept in electric circuits.

Electric Current is the flow of electrons in a conductor, measured in amperes, and is a fundamental concept in understanding electrical circuits and devices.

Electric resistance is the opposition to the flow of an electric current and is measured in ohms, representing how much a material hinders electric current flow.

How to calculate Power given Electric Current and Resistance

Let's assume the following values:

Using the formula:

\[ P = I^2 \cdot R \]

Evaluating:

\[ P = 2.1^2 \cdot 15 \]

The Power is 66.15 W.
