Question

a stepped resistor: a) has two or more fixed resistance values b) has a specific value of resistance c) changes resistance as the wiper moves d) fixes problems with resistance in a circuit

Explanation:

A stepped resistor is composed of multiple fixed - value resistors. It has two or more fixed resistance values that can be selected. Option B describes a fixed resistor, option C describes a potentiometer (variable resistor with a wiper), and option D is not a correct description of a stepped resistor's function.

Answer:

A. has two or more fixed resistance values
