Components of a transformer include core, windings, and insulation.
Core: Provides a path for magnetic flux
Windings: Primary and secondary coils for inducing voltage
Insulation: Prevents short circuits and ensures safety
MCB is a miniature circuit breaker used for low voltage applications, while MCCB is a molded case circuit breaker used for higher currents and voltages.
MCB is designed for low voltage applications, typically up to 1000V, while MCCB is designed for higher currents and voltages, typically up to 2500V.
MCB is usually thermal-magnetic in operation, while MCCB can be thermal-magnetic or electronic trip units.
MCB is compact i...
Different types of breakers include circuit breakers, fuse breakers, and ground fault circuit interrupters.
Circuit breakers: Automatically switch off electrical circuits during abnormal conditions.
Fuse breakers: Use a fuse to interrupt the circuit when overloaded.
Ground fault circuit interrupters (GFCI): Detect imbalances in current flow to prevent electrical shocks.
Miniature circuit breakers (MCB): Provide protection ...

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.
Ohm's law is represented by the equation I = V/R, where I is the current, V is the voltage, and R is the resistance.
It is named after Georg Simon Ohm, a German physicist who first formulated this law.
This law is applicable to all types of circuits, including DC and AC circuits.
It is use...
I applied via Walk-in and was interviewed in Mar 2023. There were 4 interview rounds.
The Loto system stands for Lockout/Tagout, a safety procedure used to ensure that dangerous machines are properly shut off and not started up again during maintenance or servicing.
Loto system involves locking the energy-isolating devices with individual lockout devices to prevent the machine from being turned on
Tagout involves placing a tag on the locked device to indicate that it should not be operated
