Before we dive into the details of the calculation, let's explore some interesting facts about electric potential energy:
The electric potential energy between two point charges can be calculated using the following formula:
In this formula:
The formula calculates the electric potential energy between two charges based on their magnitudes and the distance separating them. It quantifies the amount of work required to move the charges against the electric field.
Let's consider an example to see how electric potential energy is used in real-life applications. One practical application of electric potential energy is in a capacitor, which is a device used to store electrical energy.
Suppose we have a capacitor with a capacitance of 10 microfarads (μF) and a voltage of 100 volts (V). We can calculate the electric potential energy stored in the capacitor using the formula.
First, we need to convert the capacitance from microfarads to farads:
Next, we can substitute the values into the formula to calculate the electric potential energy:
Substituting the given values:
Calculating the expression:
Therefore, the electric potential energy stored in the capacitor is 0.005 joules (J).
This example demonstrates how electric potential energy is used to quantify the energy stored in a capacitor. It is an essential concept in designing and analyzing electrical circuits and systems.
