Current is the flow of electric charge in a circuit.
Current is measured in Amperes (A)
It is the rate of flow of electric charge
Current flows from high voltage to low voltage
In a series circuit, the current is the same at all points
In a parallel circuit, the total current is the sum of the currents through each branch
Soft starters are preferred over star-delta starters for motor start and run due to their ability to reduce inrush current and provide smoother acceleration.
Soft starters provide a gradual increase in voltage to the motor, reducing inrush current and mechanical stress on the motor.
Star-delta starters provide a sudden increase in voltage, resulting in high inrush current and mechanical stress on the motor.
Soft starters ...
Encoders used in industrial include absolute, incremental, linear, rotary, magnetic, and optical encoders.
Absolute encoders provide a unique code for each position
Incremental encoders provide a pulse output for each position change
Linear encoders measure linear motion
Rotary encoders measure rotational motion
Magnetic encoders use a magnetic field to detect position
Optical encoders use light to detect position
VFD parameters are settings that control the operation of a variable frequency drive.
VFD parameters include frequency, voltage, current, acceleration/deceleration time, and motor overload protection
Frequency parameter determines the speed of the motor
Voltage parameter determines the amount of voltage supplied to the motor
Current parameter determines the amount of current supplied to the motor
Acceleration/deceleration t...

I applied via campus placement at Walchand College of Engineering, Sangli and was interviewed in Jul 2024. There were 2 interview rounds.
The first round was a gamified aptitude test, and shortlisting was conducted based on sectional cutoffs. Female candidates were given higher preference.
Circuit breakers are devices that automatically stop the flow of electricity when a fault is detected, while relays are switches that open or close circuits based on electrical signals.
Circuit breakers are designed to protect electrical circuits from damage caused by overcurrent or short circuits.
They work by detecting abnormal current flow and quickly interrupting the circuit to prevent damage.
Relays are electromechan...
A Buchholz relay is a protective device used in oil-filled transformers to detect and prevent internal faults.
Detects faults such as insulation breakdown or arcing within the transformer
Consists of a float switch connected to an alarm or trip circuit
When gas or oil accumulates due to a fault, the float rises and triggers the alarm or trip signal
Helps prevent major damage to the transformer by isolating it from the powe
Induction motor operates on the principle of electromagnetic induction. Mutual inductance is the measure of the coupling between two coils.
Induction motor works on the principle of electromagnetic induction where a rotating magnetic field is produced to induce current in the rotor, causing it to rotate.
Mutual inductance is the measure of the coupling between two coils, indicating how much of the magnetic field produced...
