Q. 

Potetiometer is the example of _______ type resistor.

• Fixed

• Variable

• Both

• None of the Above

Resistors can be divided into 2 broad categories. They are:

• big and small resistors

• round and square resistors

• fixed and variable resistors

• black and white resistors

The ___ resistor is the most frequently used type of resistor.

• wire wound

• metal film

• chip resistors

• carbon composition

The 3 basic types of FIXED resistors, based on their construction are:

• Carbon composition, film and rheostats

• Carbon composition, film and wire wound

• Carbon composition, film and potentiometers

• Carbon composition, wire wound and rheostats
