Ola Electric Mobility Diagnostic Engineer Interview Questions and Answers

MOSFET is a type of transistor that uses an electric field to control the flow of current.

• MOSFET stands for Metal-Oxide-Semiconductor Field-Effect Transistor.

• It has three terminals: gate, source, and drain.

• The gate terminal controls the flow of current between the source and drain.

• MOSFET operates in three regions: cutoff, triode, and saturation.

• It is commonly used in amplifiers, switches, and digital circuits.

Relays are electrically operated switches that open and close circuits. IPM motors use power transistors to control the motor speed and direction with a DC battery supply.

• Relays work by using an electromagnet to mechanically switch contacts open or closed.

• IPM motors use power transistors to control the motor's speed and direction by adjusting the voltage and current supplied to the motor.

• DC battery supply provides the ...read more

Electric vehicles typically use AC induction motors or permanent magnet motors.

• AC induction motors are commonly used in electric vehicles due to their simplicity and reliability.

• Permanent magnet motors are also popular for their high efficiency and compact size.

• Examples of electric vehicles using AC induction motors include Tesla Model S and Nissan Leaf.

• Examples of electric vehicles using permanent magnet motors includ
