Ohm's Law Calculator Formula

V = I × R

  • V = Voltage (in volts)
  • I = Current (in amperes)
  • R = Resistance (in ohms)

Solved Illustrated Examples:
Example 1: Calculate the voltage across a resistor with a resistance of 50 ohms and a current of 2 amperes.
Resistance (R) = 50 ohms
Current (I) = 2 amperes
Using Ohm's Law formula: V = I × R
Substitute the given values:
Voltage (V) = 2 A × 50 ohms
Voltage (V) = 100 volts
Therefore, the voltage across the resistor is 100 volts.

Example 2: Determine the current flowing through a circuit with a voltage of 12 volts and a resistance of 4 ohms.
Voltage (V) = 12 volts
Resistance (R) = 4 ohms
Using Ohm's Law formula: I = V / R
Substitute the given values:
Current (I) = 12 V / 4 ohms
Current (I) = 3 amperes
Therefore, the current flowing through the circuit is 3 amperes.

Example 3: Find the resistance of a resistor if a voltage of 24 volts is applied and a current of 3 amperes flows through it.
Voltage (V) = 24 volts
Current (I) = 3 amperes
Using Ohm's Law formula: R = V / I
Substitute the given values:
Resistance (R) = 24 V / 3 amperes
Resistance (R) = 8 ohms
Therefore, the resistance of the resistor is 8 ohms.
