1. What Is The Secondary Voltage Greater Than Capacitor Voltage In Potential Divider?

The Secondary Voltage Greater Than Capacitor Voltage In Potential Divider refers to the phenomenon where the output voltage across one capacitor in a capacitive potential divider is higher than the input voltage. This occurs due to the capacitive reactance and the division of voltage across series capacitors.

2. How Does The Calculator Work?

The calculator uses the formula:

\[ V_s = \frac{(C_1 + C_2) \times V_m}{C_1} \]

Where:

\( V_s \) — Source Voltage (Volt)
\( C_1 \) — Capacitance 1 (Farad)
\( C_2 \) — Capacitance 2 (Farad)
\( V_m \) — Meter Voltage (Volt)

Explanation: This formula calculates the source voltage required to produce a specific meter voltage across capacitor C1 in a capacitive potential divider circuit.

3. Importance Of Source Voltage Calculation

Details: Accurate source voltage calculation is crucial for designing capacitive voltage divider circuits, ensuring proper voltage distribution, and preventing component damage in electronic systems.

4. Using The Calculator

Tips: Enter capacitance values in Farads and meter voltage in Volts. All values must be valid (capacitances > 0, voltage ≥ 0).

5. Frequently Asked Questions (FAQ)

Q1: Why can secondary voltage be greater than capacitor voltage?
A: In capacitive dividers, the voltage across smaller capacitors can be higher due to the inverse relationship between capacitance and voltage in series circuits.

Q2: What are typical applications of capacitive voltage dividers?
A: Used in high-voltage measurement, power transmission systems, and electronic circuits where resistive dividers would cause power loss.

Q3: How does frequency affect capacitive voltage division?
A: Capacitive reactance varies with frequency, so the voltage division ratio changes with different frequencies in AC circuits.

Q4: Are there limitations to this calculation?
A: This calculation assumes ideal capacitors and doesn't account for parasitic elements, leakage currents, or frequency effects in real-world applications.

Q5: Can this formula be used for AC circuits?
A: Yes, but the calculated values represent RMS voltages in AC applications, and the formula assumes the capacitors are purely reactive.
