Amps to Volts Formulas

Using Power (Watts):

DC: V(V) = P(W) / I(A)

AC Single Phase: V(V) = P(W) / (PF × I(A))

AC Three Phase: V(V) = P(W) / (√3 × PF × I(A))

Using Resistance (Ohms):

V(V) = I(A) × R(Ω)

Where:

  • V(V) = Voltage in volts
  • I(A) = Current in amps
  • P(W) = Power in watts
  • R(Ω) = Resistance in ohms
  • PF = Power Factor
  • √3 = 1.732 (square root of 3)

How to Convert Amps to Volts

To convert amps to volts, follow these steps:

  1. Select the calculation type (Using Power or Using Resistance)
  2. Enter the current in amps
  3. Enter either power in watts or resistance in ohms depending on your selection
  4. For AC circuits, select the phase type and enter power factor if required
  5. Click "Calculate" to get the voltage in volts
  6. Use "Reset" to clear all inputs and results

Calculation Methods

Method When to Use Formula
Using Power When you know the power consumption V = P / I (DC)
V = P / (PF × I) (AC)
Using Resistance When you know the circuit resistance V = I × R

Understanding the Results

The calculator provides voltage based on Ohm's Law (V = I × R) or power formulas. For AC circuits, the power factor accounts for the phase difference between voltage and current.
