Today we are Going to Provide You Electrical engineering interview questions from Electrical Engineering Basics Chapter.

All matter is composed of - Atoms

To be a conductor, the substance must contain some mobile electrons

Conductivity depends on the number of electrons. - (Yes/No)

The energy level of an electron decreases as its distance from the nucleus increases.  - (Yes/No)

Atoms with fewer than four valence electrons are good conductors.

Atoms with more than four valence electrons are poor conductors.

Atoms with four valence electrons are - semi-conductors

Mass of an electron is approximately equal to 1/1000 mass of the proton - (Yes/No)

The diameter of an electron = 10-15 Meter (Yes/No)

When an electron is removed from a neutral atom, this atom becomes positively charged and is called a - Positive Ion

The controlled movement of electrons through a substance is called - Current

The opposition to the flow of electrons is called electrical resistance

The practical unit of electric resistance is mho. (Yes/No)

Resistivity of a material may be defined as the resistance between the opposite faces of a meter cube of that material.

The reciprocal of specific resistance of a material is called its conductivity

The unit of conductivity is ohm/ meter. (Yes/No)

The resistance of metal conductors increases with rising of temperature. (Yes/No)

The resistance of semiconductors and all electrolytes decreases as the temperature rises.

A linear resistor is one which Obey's Ohm's law.

At very low temperature, some metals acquire zero electrical resistance and zero magnetic induction, the property known as super-conductivity
