Electron Charge Formula:
From: | To: |
The electron charge calculation determines the total electric charge based on the number of electrons. The elementary charge (e) is a fundamental physical constant equal to approximately 1.602 × 10⁻¹⁹ coulombs.
The calculator uses the electron charge formula:
Where:
Explanation: Each electron carries a fundamental charge of approximately 1.602 × 10⁻¹⁹ coulombs. The total charge is simply the number of electrons multiplied by this elementary charge.
Details: Calculating electric charge is fundamental in physics and electrical engineering for understanding electrical phenomena, circuit design, and electromagnetic theory.
Tips: Enter the number of electrons as a whole number. The calculator will compute the total charge in coulombs.
Q1: What is the elementary charge value?
A: The elementary charge is approximately 1.60217662 × 10⁻¹⁹ coulombs, which is the electric charge carried by a single proton or electron.
Q2: Can this calculator handle fractional electrons?
A: No, since electrons are discrete particles, the number of electrons must be a whole number (integer).
Q3: What units are used for charge?
A: The result is given in coulombs (C), which is the SI unit of electric charge.
Q4: How precise is the elementary charge value?
A: The value 1.6 × 10⁻¹⁹ C is an approximation. For most educational purposes, this precision is sufficient.
Q5: What's the charge of a single electron?
A: A single electron has a charge of approximately -1.602 × 10⁻¹⁹ coulombs (the negative sign indicates it's a negative charge).
