1. What is a Volts to Watts Calculator?

Definition: This calculator estimates electrical power in watts based on voltage and current.

Purpose: It helps electricians, engineers, and DIYers determine power consumption or generation in electrical circuits.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P \) — Power (watts)
• \( V \) — Voltage (volts)
• \( I \) — Current (amps)

Explanation: The voltage is multiplied by current to calculate the electrical power in watts.

3. Importance of Power Calculation

Details: Proper power calculation ensures correct circuit design, proper component selection, and electrical safety.

4. Using the Calculator

Tips: Enter the voltage in volts and current in amps. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between volts and watts?
A: Volts measure electrical potential, while watts measure power (rate of energy transfer).

Q2: Can I calculate watts with resistance instead of current?
A: Yes, using P = V²/R, but this calculator uses the basic P = V × I formula.

Q3: Is this for AC or DC circuits?
A: This calculates real power for DC circuits. For AC, you'd need to consider power factor.

Q4: How do I find current if I know watts and volts?
A: Use I = P/V. We may add this calculation in a future version.

Q5: What's a typical household voltage?
A: In North America, 120V for most outlets and 240V for large appliances.
