Glen Appliances Quality Control Incharge Interview Questions and Answers

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.

• Transformers are used to increase or decrease the voltage in electrical power applications.

• They consist of two coils of wire, known as the primary and secondary windings, wrapped around a core made of ferromagnetic material.

• Examples of transformers include power transformers used in elec...read more

The refrigerator cycle is a thermodynamic cycle that allows a refrigerator to remove heat from a low-temperature reservoir and transfer it to a high-temperature reservoir.

• The cycle typically consists of four processes: compression, condensation, expansion, and evaporation.

• During compression, the refrigerant gas is compressed, which increases its temperature and pressure.

• In the condensation process, the hot refrigerant ...read more

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, voltage, or resistance in a circuit when the other two values are known.

• For example, if a circuit has a v...read more

Ohm's law formula states that the current flowing through a conductor is directly proportional to the voltage across it and inversely proportional to its resistance.

• Ohm's law formula: V = I * R

• V represents voltage in volts, I represents current in amperes, and R represents resistance in ohms

• The formula can be rearranged to find current (I = V / R) or resistance (R = V / I)

• Ohm's law is commonly used in electrical engine...read more
