Medha Servo Drives Interview Questions, Process, and Tips

Q1. Transformer principle
Ans. 
Transformer principle involves electromagnetic induction to transfer electrical energy between two or more circuits.
• Transformers work based on Faraday's law of electromagnetic induction.

• They consist of primary and secondary coils wound around a core.

• Step-up transformers increase voltage while step-down transformers decrease voltage.

• Efficiency of transformers is determined by the ratio of output power to input power.

Q1. Draw the diagram of center tapped half wave rectifier
Ans. 
A center tapped half wave rectifier is a type of rectifier circuit that uses a center tapped transformer to convert AC to pulsating DC.
• The center tapped half wave rectifier consists of a transformer with a center tap on the secondary winding, a diode, and a load resistor.

• During the positive half cycle of the input AC signal, the diode conducts and current flows through the load resistor in one direction.

• During the nega...read more

Q2. Difine OHM's law
Ans. 
OHM's law states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor.
• Current (I) is directly proportional to Voltage (V) and inversely proportional to Resistance (R): I = V/R

• It helps in calculating the relationship between voltage, current, and resistance in an electrical circuit.

• It was named after German p...read more

Q3. Unit of capacitance
Ans. 
The unit of capacitance is farad (F).
• The unit of capacitance is named after Michael Faraday.

• 1 farad is equal to 1 coulomb per volt.

• Commonly used prefixes for capacitance include microfarad (uF) and picofarad (pF).
