Heat exchangers are devices used to transfer heat between two or more fluids.
Heat exchangers are commonly used in HVAC systems, refrigeration units, and power plants.
They work by transferring heat from one fluid to another without the fluids mixing.
Types of heat exchangers include shell and tube, plate, and finned tube.
Examples of heat exchangers include radiators in cars and condensers in air conditioning units.

I appeared for an interview in Feb 2025, where I was asked the following questions.
DC motors are classified into several types based on their construction and operation, including brushed and brushless variants.
Brushed DC Motor: Uses brushes for commutation; common in toys and small appliances.
Brushless DC Motor: No brushes; used in computer fans and electric vehicles.
Series DC Motor: High starting torque; ideal for cranes and electric trains.
Shunt DC Motor: Constant speed; used in lathes and conveyo...
Applying DC to a transformer can cause overheating and damage due to lack of magnetic flux change.
Transformers operate on the principle of electromagnetic induction, which requires alternating current (AC).
When DC is applied, it creates a constant magnetic field, leading to core saturation.
Core saturation results in excessive current draw, potentially damaging the transformer windings.
For example, a transformer rated f...

Identify missing component values in electrical circuits using Ohm's Law and circuit analysis techniques.
Use Ohm's Law (V = IR) to find missing voltage, current, or resistance values.
Apply Kirchhoff's Voltage Law (KVL) to analyze closed loops in circuits.
Utilize Kirchhoff's Current Law (KCL) to evaluate current at junctions.
Example: In a series circuit, if R1 = 10Ω and R2 = 20Ω, total resistance R_total = R1 + R2 = 30Ω...
