Conversion using the Volts to Amps Formula

Volts to Amps with Watts Calculation formula

The Phase Current I in amps is Calculated as the Real Power p in watts, divided by the Voltage in volts. Plug these values into the formula:

Current(I) = Real Power(P) Voltage(V)

or, I(A) = P(W) V(V)

or, Amps = Watts Volts

For Example, let's calculate the amperage of a 600W light bulb at 12 volts.

Volts to Amps with ohms Calculation formula

The Phase Current I in amps is Calculated as the Voltage in volts, divided by the Resistor in ohm. Plug these values into the formula:

Current(I) = Voltage(V) Resistor(R)

or, I(A) = V(V) R(ohm)

or, Amps = Volts Ohm

For Example, let's find the current of a 48v circuit with 12 ohms of resistance.

Frequently Asked Questions - FAQs for Volts to Amps Calculator

What is 1 amp?

1 ampere is the current in which 1 coulomb of charge travels across a given point in 1 second

What is the amp formula?

Examples: 6500W / 220V = 29.5A. or, 8500W / 220V = 38.6A.

What is 1 volt?

1 Volt is defined as energy consumption of 1 joule per electric charge of 1 coulomb. 1V = 1J/C.

How to calculate volts?

When spelled out, it means voltage = current (A) x resistance (ohm), or volts = amps x ohms, or V = A x Ω.

What is a Real power unit?

unit of Real Power is a Watt (W). In other terms, we spent 1 Watt of Real Power while completing 1 Joule of Work in 1 second. 1 Watt = 1 Joule / 1 second.
