Ohm's Law Current
Compute current from voltage and resistance.
Ideal calculation; real circuits may have additional factors.
Examples
- 12 V and 6 Ω ⇒ 2 A
- 5 V and 10 Ω ⇒ 0.5 A
FAQ
What is Ohm's Law?
It states that voltage = current × resistance.
Can resistance be zero?
No, dividing by zero is undefined and not physical.
Does it work for AC?
For simple resistive circuits, yes.
Which unit is current?
The result is in amperes (A).

Keep current traceable to the SI
Reviewing the formal definition in the ampere base unit guide helps you document where each ampere value originates, especially when pairing this calculator with ISO 80000-6 terminology for lab reports and compliance notes.
