Amps to Volts Conversion Formulas Calculator

Amps to Volts Conversion calculator is used to calculate voltage from known value of current and resistance or power.

To convert amps to volts:

  1. Either Current in amps and Power in watts should be known
  2. OR Current in amps and Resistance in ohms should be known

Formulas:

Voltage = Power/Amperes ( V = P/I)

Voltage = Current * Resistance ( V = IR)

Calculating Voltage from Current and Power

Example: A circuit component dissipates 1-watt power while 5 Amps current flows through it. Calculate the voltage in volts.

Solution: V = P/I = 1/5 = 0.2 Volts

How to calculate using the calculator

Step 1: Check the boxes besides Amps and Watts:

Step 2: Enter current in the box next to Amps. Here 5 Amps.

Step 3: Enter power in the box next to watts. Here 1 watt

Step 4: Hit Solve button

Both volts and ohms will be computed.

Calculating Voltage from Current and Resistance

Example: Calculate the voltage drop across 1 kΩ resistance that has 1 mA current flowing through it.

Solution: V = IR = 1 mA * 1 kΩ = 1 V

How to calculate using ElectricalCalculators.org calculator

Step 1: Check the Ohms and Amps checkboxes

Step 2: Enter current in Amps box and choose mA from prefix selector.

Step 3: Enter resistance in ohms box and choose kΩ from prefix selector.

Step 4: Hit solve button

So that was all about the Amps to Volts Conversion Formulas Calculator.
