1. What is the Charge Equation?

The charge equation (Q = C × V) calculates the electric charge stored in a capacitor, where Q is the charge in coulombs, C is the capacitance in farads, and V is the voltage in volts.

2. How Does the Calculator Work?

The calculator uses the charge equation:

\[ Q = C \times V \]

Where:

Explanation: The equation shows the direct proportionality between charge and both capacitance and voltage in a capacitor.

3. Importance of Charge Calculation

Details: Calculating electric charge is fundamental in circuit design, energy storage systems, and understanding capacitor behavior in electronic circuits.

4. Using the Calculator

Tips: Enter capacitance in farads and voltage in volts. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

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

Q2: How does capacitance affect charge?
A: For a given voltage, a larger capacitance will store more charge.

Q3: What happens to charge when voltage increases?
A: Charge increases linearly with voltage when capacitance is constant.

Q4: Can charge be negative?
A: Yes, charge can be negative, representing an excess of electrons.

Q5: How is this different from current?
A: Charge (Q) is a quantity, while current (I) is the rate of charge flow over time (I = ΔQ/Δt).
