Note, For higher values like 5×10^{3}, 10×10^{6}, 1.6 x10^{12}, enter the value like this for scientific notation as 5e3, 10e6, 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 24volt circuit with 10 ohms of resistance.
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 500watt light bulb at 24 volts.
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
1 ampere is the current in which 1 coulomb of charge travels across a given point in 1 second.
Examples: 5500 Watts / 220 Volts = 25 Amps. 8580 Watts / 220 Volts = 39 Amps.
1 Volt is defined as energy consumption of 1 joule per electric charge of 1 coulomb. 1V = 1J/C.
When spelled out, it means voltage = current (A) x resistance (ohm), or volts = amps x ohms, or V = A x Ω.
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.
