Force your doing it purposely and acceleration it’s just happening
Answer:
P = I V power produced by source at voltage V thru resistance R
I = V / R current thru resistance R
P = V^2 / R
Power produced will decrease as the output resistance R increases
Check: if R increases to ∞ the power produced will go to zero
