Q4. Which material is zero temperature coefficients
Ans. 
The material with zero temperature coefficients is called a zero temperature coefficient material (ZTC).
• ZTC materials have a constant resistance over a wide range of temperatures.

• Examples of ZTC materials include copper, gold, and platinum.

• These materials are commonly used in precision resistors and temperature sensors.

• ZTC materials are also used in electronic circuits to compensate for temperature changes.

Q5. What is the use of megger
Ans. 
A megger is used to measure the insulation resistance of electrical equipment and wiring.
• It helps to detect any insulation breakdown or leakage in electrical systems.

• It is commonly used in the maintenance and testing of transformers, motors, generators, and cables.

• The megger applies a high voltage to the equipment being tested and measures the resistance of the insulation.

• The readings obtained from the megger can help ...read more
