ASB Solutions Interview Questions and Answers

Resistance is the opposition to the flow of electric current, while voltage is the force that drives the current.

• Resistance is measured in ohms and is determined by the material and dimensions of the conductor.

• Voltage is measured in volts and is the potential difference between two points in a circuit.

• The relationship between resistance, voltage, and current is described by Ohm's Law: V = IR.

• In a circuit with multiple resistors, the voltage is divided between them according t...read more

Induction motor and universal motor are different in terms of construction, operation, and applications.

• Induction motor is AC motor while universal motor is DC motor

• Induction motor is used for high power applications while universal motor is used for low power applications

• Induction motor has a stator and a rotor while universal motor has a commutator and brushes

• Induction motor is more efficient than universal motor

• Induction motor is used in industrial applications while unive...read more

Electric current is the flow of electric charge through a conductor.

• Electric current is measured in amperes (A)

• It is caused by the movement of electrons

• Direct current (DC) flows in one direction while alternating current (AC) changes direction periodically

• Electric current is used to power electrical devices such as lights, motors, and computers

A p-n junction is the boundary between a p-type and n-type semiconductor material, forming a diode.

• It is a type of semiconductor junction formed by doping two different types of semiconductors.

• The p-type semiconductor has an excess of holes, while the n-type semiconductor has an excess of electrons.

• When the two types of semiconductors are brought together, the electrons and holes diffuse across the junction, creating a depletion region.

• This depletion region acts as a barrier ...read more

Conductors allow free flow of electrons while semiconductors have limited flow due to their structure.

• Conductors have high conductivity while semiconductors have moderate conductivity.

• Conductors have low resistance while semiconductors have high resistance.

• Examples of conductors include metals like copper and aluminum while examples of semiconductors include silicon and germanium.
