Note, For higher values like 5×103, 10×10-6, 1.6 x1012, enter the value like this for scientific notation as 5e3, 10e-6, 1.6e12, etc.

Conversion Using the Power Formula :

AC Single Phase Volts to Amps with ohms Calculation:

The Current (I) in amps (A) is equal to the voltage in volts (V) divided by the Resistance (R) in ohms (Ω):

For example, let’s find the current of a 24-volt circuit with 10 ohms of resistance.

I(A) = V(V) ÷ R(Ω)
A = 24 ÷ 10
A = 2.4

AC Single Phase Volts to Amps with Watts Calculation:

The Current (I) in amps (A) is equal to the power (P) in watts (W), divided by the voltage in volts (V):

For example, let’s calculate the amperage of a 500-watt light bulb at 24 volts.

I(A) = P(W) ÷ V(V)
A = 500 ÷ 24
A = 20.8

Where:

    • I = Current in Amps (A)
    • V = Voltage in volts (V)
    • R = Resistor In ohms (Ω)
    • P = Real Power in Watts (W)

Frequently asked questions

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: 5500 Watts / 220 Volts = 25 Amps. 8580 Watts / 220 Volts = 39 Amps.

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.
