As more resistors are added in series to a constant voltage source, the power supplied by the source Group of answer choices increases. decreases. does not change. increases for a time and then starts to decrease.

Respuesta :

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
