Textbook Problem

While testing variable resistors: Technician A says that while checking a rheostat with a voltmeter, the voltage should change smoothly with a change in the control. Technician B says that a potentiometer can be checked with a scope. Who is correct?

  1. Technician A

  • Technician B
  • Both A and B
  • Neither A nor B
  • To determine

    While testing variable resistors: The technician with correct approach.

    Explanation

    Given:

    Technician A says that while checking a rheostat with a voltmeter, the voltage should change smoothly with a change in the control.

    Technician B says that a potentiometer can be checked with a scope.

    Variable resistors help to identify the value of resistance within a specified range. They can be measured with an ohmmeter or voltmeter...
