A generator is a device that converts mechanical energy into electrical energy.
Generates electricity through electromagnetic induction
Common types include diesel generators, gas generators, and wind turbines
Used in power plants, homes, and businesses for backup power
A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction.
Consists of two coils of wire, known as primary and secondary coils
Primary coil receives electrical energy and creates a magnetic field
Magnetic field induces a voltage in the secondary coil, transferring energy
Used to step up or step down voltage levels in power distribution
Examples include power tr...
I applied via Approached by Company and was interviewed in Feb 2022. There were 2 interview rounds.
Underground cables typically have multiple layers for insulation and protection.
Underground cables usually have three layers: conductor, insulation, and protective sheath
The conductor layer carries the electrical current
The insulation layer prevents leakage of current and protects against environmental factors
The protective sheath provides additional protection from moisture, chemicals, and physical damage

A circuit breaker is an automatic electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit.
It is a safety device that automatically interrupts the flow of current in a circuit when it exceeds a safe level
It is used to protect electrical equipment from damage due to overcurrent
It can be reset after tripping, unlike a fuse which needs to be replaced
It comes in different ...
DC motors and AC motors are two types of electric motors commonly used in various applications.
DC motors operate using direct current, while AC motors operate using alternating current.
DC motors are typically used in applications that require high torque at low speeds, such as in electric vehicles and robotics.
AC motors are commonly used in household appliances, industrial machinery, and HVAC systems.
DC motors are simp...

Capacitance is the ability of a body to store an electric charge. Inductance is the ability of a coil to store energy in a magnetic field.
Capacitance is measured in Farads (F)
Capacitors are used to store energy in electronic circuits
Inductance is measured in Henrys (H)
Inductors are used in electronic circuits to store energy in a magnetic field
Both capacitance and inductance are important in AC circuits
Different types of cables used for transmissions include coaxial, twisted pair, fiber optic, and ribbon cables.
Coaxial cables are used for high-frequency transmissions and have a copper core surrounded by insulation and a braided shield.
Twisted pair cables are used for low-frequency transmissions and have two insulated copper wires twisted together.
Fiber optic cables use light to transmit data and are made of glass or ...
