Resistance values are often color coded on resistors to easily identify their resistance value.
Color coding is used on resistors to indicate their resistance value
The colors represent numbers according to a specific color code chart
The first two bands represent the first two digits of the resistance value, the third band represents the multiplier, and the fourth band represents the tolerance
For example, a resistor with...
The symbol of a diode is an arrow pointing towards a line, representing the flow of current in one direction only.

I was interviewed before Feb 2024.
The role of APFC (Automatic Power Factor Controller) is to maintain the power factor of electrical systems by automatically switching capacitors in and out of the circuit.
APFC monitors the power factor of the system and activates or deactivates capacitors accordingly.
It helps in reducing electricity bills by improving power factor and reducing reactive power consumption.
APFC ensures efficient utilization of electrical ...
Transformation ratio is the ratio of the number of turns in the primary winding to the number of turns in the secondary winding of a transformer.
Transformation ratio determines the voltage transformation between the primary and secondary windings of a transformer.
It is calculated as the ratio of the number of turns in the primary winding to the number of turns in the secondary winding.
For example, if a transformer has ...

Current is the flow of electric charge in a circuit.
Current is measured in Amperes (A)
It is the rate of flow of electric charge through a conductor
Direct current (DC) flows in one direction, while alternating current (AC) changes direction periodically
A circuit breaker is an electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit.
Circuit breakers detect faults in the electrical system and interrupt the flow of electricity to prevent damage.
They consist of a switch mechanism and a tripping mechanism that activates when a fault is detected.
Circuit breakers can be reset manually or automatically after tripping.
Example...
A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
Consists of two coils of wire (primary and secondary) wrapped around a core
Primary coil receives electrical energy and creates a magnetic field
Magnetic field induces a voltage in the secondary coil, transferring energy
Used in power distribution, voltage regulation, and electrical isolati...

The refrigeration cycle is a process of removing heat from a space or substance. Types of chillers include absorption, centrifugal, and reciprocating.
The refrigeration cycle involves four main components: compressor, condenser, expansion valve, and evaporator
Absorption chillers use a heat source to drive the refrigeration cycle, while centrifugal and reciprocating chillers use mechanical energy
Centrifugal chillers are ...

Chillers operate by removing heat from a liquid through a refrigeration cycle.
Chillers use a compressor to compress refrigerant gas, which then condenses into a liquid.
The liquid refrigerant is then pumped through an evaporator, where it absorbs heat from the chilled water.
The refrigerant then returns to the compressor to repeat the cycle.
Chillers can be air-cooled or water-cooled, depending on the application.
Chillers...
Actuator is a device that converts electrical energy into mechanical motion.
Actuators are used in HVAC systems to control the flow of air, water, or steam.
They can be electric, pneumatic, or hydraulic.
Examples of actuators include valves, dampers, and motors.
Actuators are essential for maintaining temperature, humidity, and air quality in HVAC systems.
