Exicom Electrical Engineer Interview Questions, Process, and Tips

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

• Ohm's law is a fundamental principle in electrical engineering

• It states that the current through a conductor is directly proportional to the voltage across it

• The proportionality constant is the resistance of the conductor

• Ohm's law is often used to calculate the current, voltage, or resi...read more

A substance has resistance due to the opposition it offers to the flow of electric current.

• Resistance is caused by collisions between electrons and atoms in the substance.

• The resistance of a substance depends on its physical properties such as length, cross-sectional area, and temperature.

• Some substances have higher resistance than others, such as insulators compared to conductors.

• Resistance can be measured in ohms usi

Faraday's law states that a changing magnetic field induces an electromotive force (EMF) in a conductor.

• Faraday's law is a fundamental principle of electromagnetism.

• It explains how electric generators work.

• The law states that the magnitude of the EMF induced is proportional to the rate of change of the magnetic field.

• It is used in many applications, including transformers, motors, and generators.

Switchgear is an electrical equipment that controls, protects, and isolates electrical circuits.

• Switchgear is used to control power supply in electrical systems.

• It protects electrical equipment from damage caused by overloads, short circuits, and faults.

• Types of switchgear include low voltage, medium voltage, and high voltage switchgear.

• Relays are used in switchgear to control the flow of electricity.

• Types of relays in...read more

SCR and TRIAC are semiconductor devices used for switching and controlling power in electronic circuits.

• SCR stands for Silicon Controlled Rectifier and is a four-layer PNPN semiconductor device used for power control applications.

• TRIAC stands for Triode for Alternating Current and is a three-layer PNPN semiconductor device used for AC power control applications.

• Both devices work by controlling the flow of current throu...read more
