Ohm's law calculator ►Ohms calculationsThe resistance R in ohms (Ω) is equal to the voltage V in volts (V) divided by the current I in amps (A):The resistance R in ohms (Ω) is equal to the squared voltage V in volts (V) divided by the power P in watts (W):...
Power (watts): Voltage (volts): Current (amps): Resistance (ohms): Watt is a unit of power, within electrical systems wattage corresponds to the amount of power that an electric device uses per second.Volt is a measurement of voltage, volts represent the electrical potential difference or ...
Convert amps to volts to find the voltage across the terminals of an electrical device in volts. Enter the current in amps and the power in watts or the amps and the resistance in ohms below to calculate the voltage. Results: Learn how we calculated thisbelow ...
To calculate Amps to Volts, select with (watts or Ω) first, insert value of amps and (watts or (Ω) ohms) then press Calculate Button to get the result of volts (V). Swap to Amps to Volts calculator. Select (watts/ohms): Enter volts: V Enter watts: W Result in amps: A How...
amps = 0.83 A A 100-watt light bulb at 120 volts will draw 0.83 amps of current. Convert Volts to Amps using Resistance Ohm’s Lawprovides an alternate formula to find volts if amps and the electrical resistance are known. To calculate amps, divide the voltage by the resistance in ohms....
