Work Done By Electric Force Formula:
From: | To: |
Definition: This calculator computes the work done by electric force when a charge moves through an electric potential difference.
Purpose: It helps students and professionals in physics and electrical engineering understand and calculate energy transfer in electric fields.
The calculator uses the formula:
Where:
Explanation: The work done is equal to the charge multiplied by the potential difference it moves through.
Details: Understanding this work helps in analyzing electrical circuits, capacitor energy storage, and particle movement in electric fields.
Tips: Enter the charge in Coulombs and potential difference in Volts. Both values must be positive.
Q1: What's the unit of work done?
A: The work is measured in Joules (J), which equals 1 Coulomb-Volt (C·V).
Q2: Can the work be negative?
A: Yes, if the charge is negative or moves against the field, but this calculator assumes positive values.
Q3: How is this related to electrical energy?
A: The work done equals the change in electrical potential energy of the charge.
Q4: What's a typical charge value?
A: For electrons, q = 1.6×10⁻¹⁹ C. For capacitors, it could be microcoulombs (μC) to coulombs (C).
Q5: Does this apply to AC circuits?
A: This formula is for DC or instantaneous values in AC. For AC, you'd need to consider phase angles.
