Results

P = I²R.
200W
E = I²Rt.
12,000J

At a glance:P = I²R; E = I²Rt. Complements power and resistance.

Formula

P = I²·R.

$$P = I^2 R, \quad Q = P \cdot t = I^2 R t$$

How to Use

  1. Enter current, resistance and time.
  2. The tool returns power and energy.

Case Studies

I=2, R=5, t=10

P=20 W, E=200 J.

FAQ

Other forms?

P = V²/R = VI (same via Ohm's law).
