TDK India Private Limited Assistant Engineer Interview Questions, Process, and Tips

TPM stands for Total Productive Maintenance, a type of maintenance strategy focused on maximizing the efficiency and effectiveness of equipment.

• TPM involves proactive maintenance to prevent breakdowns and improve overall equipment effectiveness

• It emphasizes employee involvement and ownership of equipment maintenance

• TPM aims to eliminate the 6 big losses: breakdowns, setup and adjustment time, idling and minor stoppages...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

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 ...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

• Indu...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.

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...read more
