Power given Electric Potential Difference and Resistance Calculator

Calculate Power





Formula

The formula to calculate Power (P) is:

\[ P = \frac{ΔV^2}{Rp} \]

Where:

Definition

Power is the rate at which electric energy is transferred or converted, typically measured in watts.

Electric Potential Difference is the voltage across two points in a circuit, measured in volts.

Resistance for power is a measure of how much a material or component resists the flow of electric current.

How to calculate Power given Electric Potential Difference and Resistance

Let's assume the following values:

Using the formula:

\[ P = \frac{ΔV^2}{Rp} \]

Evaluating:

\[ P = \frac{18^2}{4.897} \]

The Power is 66.1629569123953.
