All of the following statements are true EXCEPT:
A) variable resistors, called rheostats or potentiometers, are also used to control the speed and intensity of electrical loads.
B) a rheostat varies current flow through the circuit as a movable wiper runs along a resistor.
C) a potentiometer varies the voltage in a circuit.
