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?
