Ohm's Law Calculator Online



The formula for calculating Current (I) is

Current (I) =
Voltage (V) / Resistance (Ω)


Example of Calculations for Current (I):

Voltage (volts): 3

Resistance (ohms Ω) : 2

Current (I) =
3 / 2
= 1.5 amps




The formula for calculating Resistance (Ω) is

Resistance (Ω) =
Voltage (V) / Current (I)


Example of Calculations for Resistance (Ω):

Voltage (volts): 3

Current (amps) : 2

Resistance (Ω) =
3 / 2
= 1.5 amps




The formula for calculating Voltage (V) is

Voltage (V) =
Resistance (Ω) x Current (I)


Example of Calculations for Voltage (V):

Resistance (ohms Ω): 3

Current (amps) : 2

Voltage (V) =
3 * 2
= 6 volts




The formula for calculating Power(watts) is

Power(watts) =
Voltage (V) x Current (I)


Example of Calculations for Power(watts):

Voltage (volts): 3

Current (amps) : 2

Power(watts) =
3 * 2
= 6 volts




The formula for calculating Voltage (V) is

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


Example of Calculations for Voltage (V):

Power (watts): 3

Current (amps) : 2

Voltage (V) =
3 / 2
= 1.5 volts




The formula for calculating Current (I) is

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


Example of Calculations for Current (I):

Power (watts): 3

Voltage (volts) : 2

Current (I) =
3 / 2
= 1.5 amps
