## Ohm's Law Voltage

##### CALCULATE VOLTAGE

This Ohm’s Law Calculator is extremely easy to use,  just enter any two values and hit “Calculate” to calculate the other two.

Calculate:

• Voltage (Volts)
• Current (Amperes)
• Resistance (Ohm’s)
• Power (Watts)

Enter any two values to calculate the other two!

##### OHMS LAW FORMULA: How to calculate voltage

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

## Ohm's Law Current

##### CALCULATE CURRENT

To calculate current with this ohms law calculator enter either two of theses options, voltage, resistance or power.

#### Ohm’s Law Symbols:

• V = Voltage
• I = Current
• R = Resistance
• P = Power

Enter any two of the above values to calculate the other two!

##### OHMS LAW FORMULA: How to calculate current

Current = V ÷ R
Voltage (V) ÷ Resistance (R) = Current (I)

## Ohm's Law Resistance

##### CALCULATE RESISTANCE

To calculate resistance enter any two of these values, Voltage, Current or Power.

#### Ohm’s Law Measurements:

• Resistance is measured in Ohms.
• Voltage is measured in Volts.
• Power is measured in Watts.
• Current is measured in Amps.

##### OHMS LAW FORMULA: How to calculate resistance

Resistance = V ÷ I
Voltage (V) ÷ Current (I) = Resistance (R)

## Ohm's Law Power

##### CALCULATE POWER

To calculate power with this Ohm’s Law Calculator enter any two of theses options, Voltage, Current or Resistance.

• Power
• Amps
• Resistance
• Voltage

## FAQ's

#### What is Ohms Law?

Ohm’s Law is a formula for calculating the relationships between Voltage, Current and Resistance.

Ohm’s law states that the current through a conductor between two points is directly proportional to the voltage across the two points. Introducing the constant of proportionality, the resistance one arrives at the usual mathematical equation that describes this relationship. Source: Wikipedia
