Question

3. The reliability of two voltmeters A and B of range 3V each is examined against a standard voltage source of emf 1.018V. The voltage of source is measured five times and the corresponding reading of voltmeters in all five sets are recorded as under in a tabular form:

s.no Reading of voltmeter A (volt) Reading of voltmeter B (volt)

1. 1.01 2.02

2. 1.07 2.04

3. 1.06 2.03

4. 1.09 2.05

5. 1.08 2.01



From the above reading, which voltmeter gives precise measurement and which has higher accuracy?
