Instantly convert amps to volts using our free calculator. Choose single or three-phase systems and input power to get accurate voltage values online.
Quick Intro: Convert Amps to Voltage
To convert amps to volts, you need to know the system type (single-phase or three-phase) and power in watts. The basic formula is: Volts = Watts / Amps. For three-phase systems, use Volts = Watts / (√3 × Amps) for line-to-line voltage. This calculator simplifies the process by automating these formulas and providing instant results for accurate voltage values.
Amps to Voltage Calculator Overview
The Amps to Volts Calculator helps you determine the voltage in an electrical circuit based on current (amps) and power (watts). Whether you're working with a single-phase or three-phase system, this tool simplifies electrical conversions. Simply enter the current in amps and the power in watts, and the voltage will be calculated automatically using the proper formula for your system type. This calculator is ideal for electricians, engineers, students, or anyone involved in electrical design and troubleshooting. You can also switch between AC and DC systems and calculate values for different voltage types (line-to-line and line-to-neutral for three-phase). It eliminates manual calculations, saves time, and ensures accuracy.
Sample Amps to Voltage conversion table
| System Type | Watts | Amps | Volts |
|---|
| Single-Phase | 2300 W | 10 A | 230 V |
| 3-Phase (L-L) | 6900 W | 10 A | 398 V |
| 3-Phase (L-N) | 6900 W | 10 A | 230 V |
| DC Circuit | 1200 W | 6 A | 200 V |
What is the formula to convert amps to volts?
Volts = Watts ÷ Amps. For 3-phase, divide by √3 × Amps.
Do I need to know power to calculate volts?
Yes, power in watts is necessary to calculate voltage from current.
What's the difference between AC and DC voltage?
AC voltage alternates direction; DC voltage flows in one direction.
What is line-to-line voltage in 3-phase?
Voltage between any two of the three phase conductors.
Can this calculator be used for DC circuits?
Yes, the formula Volts = Watts ÷ Amps works for DC as well.
Is there a difference in formula for 3-phase?
Yes, 3-phase uses √3 in the denominator for line-to-line voltage.
What is √3 and why is it used?
√3 (approx. 1.732) accounts for phase angle differences in 3-phase systems.
How accurate is this amps to volts calculator?
It provides accurate results if input values are correct.
Is line-to-neutral voltage lower than line-to-line?
Yes, it's lower by a factor of √3 in a balanced 3-phase system.
