1. What is Net Electric Charge?

The net electric charge is the algebraic sum of all individual charges in a system. It follows the principle of charge conservation, where the total charge in an isolated system remains constant.

2. How Does the Calculator Work?

The calculator uses the net charge formula:

\[ Q_{net} = \sum Q = Q_1 + Q_2 + Q_3 + \dots + Q_n \]

Where:

\( Q_{net} \) — Net electric charge (Coulombs)
\( Q_1, Q_2, \dots, Q_n \) — Individual charges (Coulombs)

Explanation: The calculator sums all positive and negative charges to determine the overall net charge of the system.

3. Importance of Net Charge Calculation

Details: Calculating net charge is fundamental in electrostatics, helping determine electric fields, forces between charged objects, and understanding electrical systems.

4. Using the Calculator

Tips: Enter charges separated by commas (e.g., "2, -3, 5, -1"). Positive and negative values are allowed. The calculator will sum all values to find the net charge.

5. Frequently Asked Questions (FAQ)

Q1: What is the unit of electric charge?
A: The SI unit of electric charge is the Coulomb (C).

Q2: Can net charge be zero?
A: Yes, when the sum of positive charges equals the sum of negative charges, the net charge is zero (electrically neutral).

Q3: What is the charge of a single electron?
A: The elementary charge is approximately -1.602 × 10^-19 C (negative for electrons, positive for protons).

Q4: How is net charge different from total charge?
A: Net charge considers the sign (positive/negative) of charges, while total charge would be the sum of absolute values.

Q5: Why is charge quantization important?
A: All observable charges are integer multiples of the elementary charge, which is fundamental to quantum electrodynamics.
