  4. The result will be displayed in amperes (A)

Ohm's Law Explanation

Ohm's Law is a fundamental principle in electrical circuits that describes the relationship between voltage, current, and resistance. It states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them.

The formula is:

I = V / R

Where:

  • I = Current (measured in Amperes, A)
  • V = Voltage (measured in Volts, V)
  • R = Resistance (measured in Ohms, Ω)

Example

If you have a circuit with a voltage of 12 volts and a resistance of 100 ohms, the current would be:

I = 12V / 100Ω = 0.12 Amperes
