1. What is Capacitor Charge?

The charge (Q) stored in a capacitor is directly proportional to the capacitance (C) and the voltage (V) across it. This fundamental relationship is described by the equation Q = C × V.

2. How Does the Calculator Work?

The calculator uses the capacitor charge equation:

Where:

• \( Q \) — Charge stored in coulombs
• \( C \) — Capacitance in farads
• \( V \) — Voltage across the capacitor in volts

Explanation: The equation shows that the amount of electrical charge a capacitor can store depends on its capacitance value and the applied voltage.

3. Importance of Charge Calculation

Details: Calculating capacitor charge is essential for designing electronic circuits, timing applications, power supply filtering, energy storage systems, and understanding capacitor behavior in various electrical applications.

4. Using the Calculator

Tips: Enter capacitance in farads and voltage in volts. Both values must be positive numbers. The calculator will compute the charge in coulombs.

5. Frequently Asked Questions (FAQ)

Q1: What units are used for capacitance?
A: Capacitance is measured in farads (F), though microfarads (μF), nanofarads (nF), and picofarads (pF) are more common in practical applications.

Q2: How does voltage affect capacitor charge?
A: The charge stored is directly proportional to the voltage applied. Doubling the voltage doubles the charge stored for a given capacitance.

Q3: What is the maximum voltage a capacitor can handle?
A: Each capacitor has a maximum voltage rating (working voltage) that should not be exceeded to prevent dielectric breakdown and capacitor failure.

Q4: How does capacitance value affect charge storage?
A: Larger capacitance values allow more charge to be stored at the same voltage. A 1 farad capacitor stores 1 coulomb per volt.

Q5: What happens during capacitor discharge?
A: When a charged capacitor is connected to a load, it releases stored energy, and the charge decreases as current flows through the circuit.
