Frequently asked questions

How is the current divided between two resistances?

The branch with less resistance receives more current.

What is the formula for I₁?

I₁ = Itotal × R₂ / (R₁ + R₂).

What is the formula for I₂?

I₂ = Itotal × R₁ / (R₁ + R₂).

Does it also show equivalent resistance?

Yes.
