Amps to VA Calculator

What is the relationship between Amps and VA?

Amperage (measured in amps) and volt-amperes (VA) are two important concepts in electrical engineering. VA is a measure of apparent power in an electrical circuit. The relationship between amps and VA is straightforward: VA equals current (in amps) multiplied by voltage (in volts).

How to convert Amps to VA

To convert amps to VA, you need to know the voltage in the circuit. The formula is:

VA = A × V

Where VA is volt-amperes, A is current (amps), and V is voltage (volts).

Example

Let's look at an example:

If a device draws 2 amps at 120 volts, what is the VA?

VA = A × V = 2 × 120 = 240 VA

Applications

Understanding the relationship between amps and VA is crucial in many areas, including:

• Electrical engineering and power system analysis
• Sizing of electrical equipment and power supplies
• UPS (Uninterruptible Power Supply) specifications
• Power factor correction in AC circuits

This calculator simplifies the process of converting between amps and VA, making it a valuable tool for professionals and hobbyists alike in the field of electronics and electrical engineering.
