1.	In a voltmeter there are 20 divisions between the 0 mark and 0.5 mark. The least count of the voltmeter is (a) 0.020 V(b) 0.025 V(c) 0.050 V(d) 0.250 V
Answer» The correct option is (b) 0.025 V. Explanation: Least count = gap between two marks (range)/ number of division = (0.5 - 0)v/20 = 0.5/20 = 0.025 V

Answer»

The correct option is (b) 0.025 V.

Explanation:

Least count = gap between two marks (range)/ number of division

= (0.5 - 0)v/20

= 0.5/20

= 0.025 V
