Question

What is the order of resistance in the following materials?

• A. Conductors $>$Semiconductors$>$Insulators
• B. Insulators$>$ Semiconductors$>$Conductors
• C. Semiconductors$>$Insulators$>$ Conductors
• D. Insulators$>$conductors$>$semiconductors

Answer 1

The correct option is B

Insulators$>$ Semiconductors$>$Conductors

Resistance is nothing but obstruction to the electron flow and conductance is ease of electron flow. So both are inversely proportional. If Resistance increases conductance decreases and if Resistance decreases conductance increases.

We already know the order of electrical conductance in materials which is

Conductors$>$Semiconductors$>$Insulators

So exact opposite order is for the resistance Insulators$>$Semiconductors$>$Conductors
