1. What is a Volts Amps Watts Calculator?

Definition: This calculator determines electrical power based on voltage and current using Ohm's Law.

Purpose: It helps electricians, engineers, and DIY enthusiasts calculate power consumption in electrical circuits.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: The product of voltage and current gives the power consumption in an electrical circuit.

3. Importance of Power Calculation

Details: Accurate power calculations ensure proper circuit design, component selection, and electrical safety.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

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

Q2: Can I calculate any two values if I know the third?
A: Yes, the formula can be rearranged: V = P/I or I = P/V.

Q3: What's a typical household voltage?
A: In North America, 120V for standard outlets and 240V for large appliances.

Q4: How does this relate to energy bills?
A: Energy companies bill in kilowatt-hours (kWh), which is power (kW) × time (hours).

Q5: What about AC vs DC power?
A: This formula works for DC. For AC, you must consider power factor (cos φ).
