1. What is Electric Charge?

Electric charge is a fundamental physical property of matter that causes it to experience a force when placed in an electromagnetic field. The SI unit of electric charge is the coulomb (C).

2. How Does the Calculator Work?

The calculator uses the electric charge equation:

Where:

• \( Q \) — Electric charge (Coulombs)
• \( I \) — Current (Amperes)
• \( t \) — Time (Seconds)

Explanation: The equation shows that electric charge is the product of current flowing and the time duration of that flow.

3. Importance of Electric Charge Calculation

Details: Calculating electric charge is essential in circuit design, battery capacity estimation, and understanding electromagnetic phenomena.

4. Using the Calculator

Tips: Enter current in amperes and time in seconds. Both values must be positive numbers.

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: How much charge does one electron have?
A: One electron has a charge of approximately -1.602 × 10⁻¹⁹ coulombs.

Q3: What's the difference between current and charge?
A: Current is the rate of flow of electric charge (Amperes = Coulombs/second), while charge is the quantity of electricity (Coulombs).

Q4: Can charge be negative?
A: Yes, charge can be positive or negative depending on the type of particles (protons are positive, electrons are negative).

Q5: How is this used in practical applications?
A: Calculating charge is important for determining battery capacity, capacitor specifications, and understanding electrical circuits.
