What type of resistor operates by moving the wiper arm with a screw of some number of turns?
A) pot
B) wire-wound
C) multiturn variable
D) rheostat
Multiturn Variable
Describes a type of variable resistor or potentiometer that allows for precise adjustment over multiple rotations of its knob or dial.
Wiper Arm
A movable contact in variable resistors or potentiometers that slides across a resistive element to vary resistance.
Wire-Wound
Referring to a type of resistor or inductor where wire is wound around a core to create electrical resistance or inductance.
