1. What is Electric Potential Energy?

Electric potential energy is the energy that a charged particle possesses due to its position in an electric field. It represents the work done to bring a charge from infinity to a specific point in the electric field.

2. How Does the Calculator Work?

The calculator uses the electric potential energy formula:

Where:

• \( PE \) — Electric potential energy (Joules)
• \( q \) — Electric charge (Coulombs)
• \( V \) — Electric potential (Volts)

Explanation: The formula calculates the energy stored in a charge due to its position in an electric potential field.

3. Importance of Electric Potential Energy Calculation

Details: Calculating electric potential energy is essential in understanding electrical systems, capacitor energy storage, and analyzing the behavior of charged particles in electric fields.

4. Using the Calculator

Tips: Enter charge in Coulombs and electric potential in Volts. Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is the unit of electric potential energy?
A: Electric potential energy is measured in Joules (J), which is equivalent to Newton-meters.

Q2: How does electric potential differ from electric potential energy?
A: Electric potential (V) is the potential energy per unit charge, while electric potential energy (PE) is the total energy a charge possesses at a point.

Q3: Can electric potential energy be negative?
A: Yes, electric potential energy can be negative when the charge is negative or when the reference point is set differently.

Q4: What are some practical applications of electric potential energy?
A: It's used in capacitor energy storage, battery systems, and understanding the behavior of charged particles in various electrical devices.

Q5: How is this related to work done in an electric field?
A: The electric potential energy represents the work done by an external agent to bring a charge from infinity to a specific point in the electric field.
