Question

Match List-I (Instrument) and List-II (Error) and select the correct answer using the code given below the lists:

List-I (Instrument)		List-II (Error)
A.	PAMC voltmeter	P.	Eddy current error
B.	AC ammeter	Q.	Phase angle error
C.	Current Transformer	R.	Braking system error
D.	Energy meter	S.	Temperature error

• A. A - Q, B - R, C - S, D - P
• B. A - S, B - P, C - Q, D - R
• C. A - P, B - Q, C - R, D - S
• D. A - S, B - R, C - D, D - P

Hint:

Understanding the typical errors associated with each type of instrument is essential for accurate measurements and calibration.

Answer 1

The Correct Option is B

- A - S: PAMC voltmeter is subject to temperature error.
- B - P: AC ammeter typically experiences eddy current error.
- C - Q: Current transformers can result in phase angle error.
- D - R: Energy meters are commonly affected by braking system error.
Thus, the correct answer is A - S, B - P, C - Q, D - R.
