Q
T

Results

Computed current I.
3
I=12/4=3 A

At a glance:I = Q/t = V/R = P/V. Complements ohms-law and charge.

Formula

I = Q / t.

I = V / R.

How to Use

  1. Pick a mode and enter the values.
  2. The tool returns the current.

Case Studies

V=12, R=4 (Ohm)

I = 3 A.

FAQ

Units?

1 A = 1 C/s = 1 V/Ω.
