Ohm’s Law I = V/R – The Foundation of Electric Current

 


The formula Ohm’s Law I = V/R defines the relationship between current (I), voltage (V), and resistance (R).

It is used to calculate how much current flows in any electrical circuit.

  • I (Current) increases when voltage increases.

  • I decreases when resistance increases.

  • This formula is essential for circuit design, load calculation, and troubleshooting.

Using accurate tools like an online electric current converter becomes much easier when you understand this basic formula.
