Transformers are electrical devices that transfer energy from one circuit to another through electromagnetic induction.
Transformers are used to increase or decrease the voltage of an alternating current (AC) power supply.
They consist of two coils of wire, known as the primary and secondary coils, wrapped around a magnetic core.
When an AC voltage is applied to the primary coil, it creates a magnetic field that induces a...

I applied via campus placement at Falakata College, Jalpaiguri and was interviewed in May 2024. There was 1 interview round.
Ohm's law states that the current flowing through a conductor is directly proportional to the voltage across it, and inversely proportional to the resistance of the conductor.
Ohm's law is represented by the formula V = I * R, where V is voltage, I is current, and R is resistance.
It helps in calculating the current flowing through a circuit when the voltage and resistance are known.
It also helps in determining the resis...

Exothermic and endothermic reactions release and absorb heat, respectively. Heat transfer is the movement of heat from one object to another through convection, conduction, or radiation.
Exothermic reactions release heat to the surroundings
Endothermic reactions absorb heat from the surroundings
Convection is heat transfer through fluid movement (e.g. boiling water)
Conduction is heat transfer through direct contact (e.g. ...

There are three laws of thermodynamics.
There are three laws of thermodynamics: the zeroth law, the first law, and the second law.
The zeroth law states that if two systems are in thermal equilibrium with a third system, they are in thermal equilibrium with each other.
The first law states that energy cannot be created or destroyed, only transferred or converted.
The second law states that the entropy of an isolated system

Grain boundaries are interfaces between grains in a polycrystalline material, affecting material properties.
Grain boundaries are regions where the crystal structure changes orientation.
They can affect material properties such as strength, conductivity, and corrosion resistance.
Grain boundaries can be classified as low-angle or high-angle boundaries based on the misorientation angle.
Examples include the use of grain bou...
