All of the Following Statements Are True EXCEPT

All of the following statements are true EXCEPT:

A) voltage differential controls how strongly a load in a circuit is operated.
B) when voltage differential is lower than normal, a light will not be as bright or a heater defroster motor will not spin as fast.
C) if voltage drops as loads are added to a circuit, flow is increased in the circuit.
D) voltage differential is the difference between battery voltage at one end of a circuit and zero voltage on the ground side.
