Current is the flow of electric charge in a circuit.
Current is measured in amperes (A).
It is caused by the movement of electrons or other charged particles.
Current can be either direct current (DC) or alternating current (AC).
In a DC circuit, current flows in one direction only, while in an AC circuit, it periodically changes direction.
Current is essential for the operation of electrical devices and is controlled by re
An amp is a unit of electric current measurement in the International System of Units (SI).
Amp is short for ampere, named after the French physicist André-Marie Ampère.
It is used to measure the flow of electric charge in a circuit.
One ampere is defined as the amount of current that flows through a conductor when a potential difference of one volt is applied across it.
Amps are commonly used to rate the capacity of elect...
I applied via Naukri.com and was interviewed in Mar 2024. There were 2 interview rounds.
A transformer works on the principle of mutual induction between two windings linked by a common magnetic flux.
Transformers consist of two inductive coils - primary and secondary windings.
When an alternating current flows through the primary winding, it creates a changing magnetic field which induces a voltage in the secondary winding.
The ratio of the number of turns in the primary winding to the number of turns in the...

DOL starter is a direct online starter used to start and stop the motor instantly.
DOL stands for Direct Online.
It is used to start and stop the motor instantly.
It is the simplest and cheapest method of starting a motor.
It consists of a contactor, overload relay, and start and stop push buttons.
It is used for small motors up to 5 horsepower.
It is not suitable for large motors as it causes a high starting current.
Example...

VFD stands for Variable Frequency Drive, used to control the speed of an AC motor by varying the frequency and voltage supplied to the motor.
VFDs are commonly used in industrial applications to control pumps, fans, and other motor-driven equipment.
They can improve energy efficiency by adjusting motor speed to match the required load.
VFDs can also provide better control over motor acceleration and deceleration, reducing...

RCCB stands for Residual Current Circuit Breaker, a device designed to quickly disconnect power in the event of a leakage current.
RCCB is a safety device used to protect against electric shock and fire hazards.
It detects any imbalance in the electrical current flowing through the circuit.
When a leakage current is detected, the RCCB trips and disconnects the power supply.
RCCBs are commonly used in residential, commercia...
