1. What is the Capacitor Voltage Equation?

The capacitor voltage equation calculates the voltage across a capacitor in an AC circuit. It is derived from the fundamental relationship between current, frequency, and capacitance in reactive circuits.

2. How Does the Calculator Work?

The calculator uses the capacitor voltage equation:

Where:

• \( V \) — Voltage across the capacitor (Volts)
• \( I \) — Current flowing through the circuit (Amps)
• \( f \) — Frequency of the AC signal (Hz)
• \( C \) — Capacitance (Farads)

Explanation: This equation calculates the voltage drop across a capacitor in an alternating current circuit, considering the capacitive reactance.

3. Importance of Voltage Calculation

Details: Accurate voltage calculation is crucial for designing and troubleshooting refrigerator circuits, ensuring proper capacitor sizing, and preventing electrical failures.

4. Using the Calculator

Tips: Enter current in amps, frequency in Hz, and capacitance in farads. All values must be valid (positive numbers).
