Q1. What is difference between RTD and thermocouple used
Ans. 
RTD measures temperature using resistance change, while thermocouple uses voltage change.
• RTD stands for Resistance Temperature Detector, while thermocouple generates voltage based on temperature difference.

• RTDs are more accurate and stable compared to thermocouples.

• RTDs have higher initial cost but lower long-term maintenance cost.

• Thermocouples are more rugged and can withstand higher temperatures than RTDs.

• Example: RT...read more

Q4. What do you understand by 4 wire and 2 wire
Ans. 
4 wire and 2 wire are configurations used in electrical circuits for measuring resistance.
• 4 wire configuration is used for accurate resistance measurements by eliminating lead resistance

• 2 wire configuration is simpler but less accurate due to lead resistance affecting measurements

• Examples: 4 wire used in precision instruments like multimeters, 2 wire used in basic circuit testing
