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 Amps to volts with ohms Calculation:
The voltage V in volts (V) is equal to the current (I) in amps (A), times the resistance R in ohms (Ω):
For example, let’s find the voltage of a circuit with 5 amps of current and 15 ohms of resistance.
V_{(V)} = 5 x 15
V_{(V)} = 75 V
AC Single Phase Amps to Volts With Watts Calculation:
The voltage V in volts (V) is equal to the Real power (P) in watts (W), divided by the current I in amps (A):
For example, let’s find the voltage of a device that uses 240 watts of power with a current of 8 amps.
V_{(V)} = 240÷ 8 V
V_{(V)} = 30V
Where:

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

Frequently asked questions
1 Coulomb / Second
Ampere = 1 Coulomb / Second.
one volt is equal to one joule of electric potential energy per(divided by) one coulomb of charge.
The amount of Real power an appliance uses is determined by its wattage. 5000 watts equals 5 kilowatt. When you run a 5000 watt appliance for an hour you use 5 units (kilowatt hour) of electricity.
When spelled out, it means voltage = current (A) x resistance (ohm), or volts = amps x ohms, or V = A x Ω.
An equivalent of the total energy supplied if electrical Real power of 1 watt is maintained for 1 hour.
