A motor converts electrical energy into mechanical energy, while a generator converts mechanical energy into electrical energy.
Motor uses electricity to produce motion, while generator uses motion to produce electricity
Motors are commonly found in appliances, vehicles, and industrial machinery
Generators are used in power plants, wind turbines, and backup power systems
I applied via Campus Placement and was interviewed in Apr 2024. There was 1 interview round.
Current is the flow of electric charge through a conductor.
Current is measured in amperes (A)
It is the rate of flow of electric charge
Direct current (DC) flows in one direction, while alternating current (AC) changes direction periodically
Resistors are electronic components that limit the flow of electric current in a circuit.
Resistors are used to control the amount of current flowing in a circuit.
They are measured in ohms (Ω) and come in various values.
Resistors can be fixed or variable depending on the application.
Examples include carbon film resistors, metal film resistors, and variable resistors like potentiometers.
A diode is a semiconductor device that allows current to flow in one direction only.
Semiconductor device
Allows current flow in one direction only
Commonly used in rectifiers and voltage regulators
Electronic components are parts that make up electronic devices and systems.
Electronic components are used to control the flow of electricity in electronic devices.
Examples of electronic components include resistors, capacitors, transistors, and diodes.
Electronic components can be classified as active or passive components.
Active components require a power source to function, while passive components do not.

I applied via Campus Placement and was interviewed before Jul 2020. There were 3 interview rounds.
There are various types of CCTV cameras such as dome, bullet, PTZ, thermal, and covert cameras.
Dome cameras are commonly used for indoor surveillance and have a wide-angle view.
Bullet cameras are weatherproof and have a longer range than dome cameras.
PTZ cameras can pan, tilt, and zoom to cover a larger area.
Thermal cameras use heat signatures to detect movement and are often used in low-light environments.
Covert camer...
CCTV stands for Closed Circuit Television. It is a system of video cameras used for surveillance and security purposes.
CCTV cameras are commonly used in public places like banks, airports, and shopping malls.
They can also be used in homes and businesses for security purposes.
CCTV footage can be used as evidence in criminal investigations.
The use of CCTV has raised concerns about privacy and civil liberties.
