1. What is a Voltage from Frequency Calculator Watts?

Definition: This calculator estimates the voltage based on power in watts and impedance in ohms.

Purpose: It helps electrical engineers and technicians determine the voltage in AC circuits when power and impedance are known.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V = \sqrt{P \times Z} \]

Where:

\( V \) — Voltage (volts)
\( P \) — Power (watts)
\( Z \) — Impedance (ohms)

Explanation: The square root of the product of power and impedance gives the voltage in the circuit.

3. Importance of Voltage Calculation

Details: Proper voltage calculation ensures safe circuit design, proper equipment operation, and efficient power distribution.

4. Using the Calculator

Tips: Enter the power in watts and impedance in ohms. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Is this formula for AC or DC circuits?
A: This formula is primarily used for AC circuits where impedance is a factor.

Q2: What's the difference between impedance and resistance?
A: Impedance includes both resistance and reactance (inductive/capacitive effects) in AC circuits.

Q3: Can I use this for three-phase systems?
A: This calculates line voltage for single-phase systems. Three-phase requires additional factors.

Q4: How does frequency affect this calculation?
A: Frequency affects impedance (Z) but not the basic voltage formula shown here.

Q5: What if I only know current, not power?
A: Use Ohm's Law (V = I × Z) if you know current and impedance instead.
