Solved from
voltage and current
Worked out from Ohm's law: V = I R, and the power relation P = V I and 1 other source.

How this is worked out

4 steps
  1. Given voltage and current.
  2. V = 12 V, I = 2 A.
  3. R = V / I = 6 ohm
  4. P = V I = 24 W
Relations usedtable
V = I R, P = V I, P = I^2 R, P = V^2 / R
