Question

The range of a voltmeter is 0 to 2.0V. If it has 20 divisions between 0 mark and 0.5 V markte
count is
[1 MARKICBSE 10TH BOARD: 21
(A) 0.020 V
(B) 0.025 V
(C) 0.050 V
(D) 0.250 V​

Answer 1

Answer:

The least count is related to the precision of an instrument. Range is basically the difference between maximum value to the minimum value. For voltmeter, there are 20 divisions for a voltmeter between 0−0.5V marks. Means 0.5 volt is equal to 20 divisions.
