Nope, wrong.
When you increase the R (resistance to decrease speed of
fan), less current is flowing in the circuit.
Recall basic formula of V = R.I ?
If R increases, I decreases.
Now, the power consumption formula being P = V.I =
R.Isquared, then if I decreases (as proved earlier) and V
stays the same, then P decreases.
There you go :)
