BKT Tyres Electrical Technician Interview Questions and Answers

DC current is the flow of electric charge in a constant direction.

• DC stands for Direct Current.

• It is the opposite of AC (Alternating Current).

• DC current flows continuously in one direction.

• It is commonly used in batteries and electronic devices.

• Examples of DC current include the current from a solar panel or the current from a car battery.

The full form of A.C. current is Alternating Current.

• A.C. current stands for Alternating Current.

• It is a type of electric current that periodically reverses direction.

• It is commonly used in household electrical systems and power grids.

• Unlike direct current (D.C.), A.C. current can easily be transformed to different voltage levels.

• Examples of A.C. current include the electricity supplied by utility companies and the pow

The full form of D.C. current is Direct Current.

• D.C. stands for Direct Current.

• It is a type of electrical current that flows in one direction only.

• It is commonly used in batteries and electronic devices.

• The opposite of D.C. current is A.C. current, which alternates direction.

• D.C. current is measured in amperes (A).

VFD stands for Variable Frequency Drive. It is used to control the speed of an electric motor.

• VFD is used to save energy and reduce wear and tear on motors.

• It can be used in HVAC systems, pumps, and fans.

• VFD works by adjusting the frequency of the electrical supply to the motor.

• It allows for precise control of motor speed and can also provide soft starting and stopping.

• VFD can also monitor and protect the motor from ov
