1. What is Net Charge?

Net charge (Q_net) is the algebraic sum of all individual charges in a system. It represents the overall charge when all positive and negative charges are combined.

2. How Does the Calculator Work?

The calculator uses the net charge equation:

\[ Q_{net} = \sum Q \]

Where:

\( Q_{net} \) — Net charge in coulombs (C)
\( \sum Q \) — Sum of all individual charges

Explanation: The equation simply adds all positive and negative charges together to determine the overall charge of the system.

3. Importance of Net Charge Calculation

Details: Calculating net charge is fundamental in electrostatics, chemistry, and physics. It helps determine electrical forces, predict chemical behavior, and analyze electrical systems.

4. Using the Calculator

Tips: Enter charges separated by commas (e.g., "2, -3, 1.5"). Positive and negative values are allowed. The calculator will sum all values to find the net charge.

5. Frequently Asked Questions (FAQ)

Q1: What units does this calculator use?
A: The calculator uses coulombs (C), the SI unit of electric charge.

Q2: How do I represent negative charges?
A: Simply prefix the charge value with a minus sign (e.g., -1.6e-19 for an electron's charge).

Q3: What's the charge of a single electron?
A: Approximately -1.602 × 10^-19 C (the elementary charge).

Q4: Can I use scientific notation?
A: Yes, you can enter values like "1.6e-19" for 1.6 × 10^-19.

Q5: What does a net charge of zero mean?
A: It means the system is electrically neutral, with equal amounts of positive and negative charge.
