Question

if the pointer of voltmeter coincides with 8th division of the scale of voltmeter. Find the reading of the voltmeter. ​

Answer 1

Answer:

Thus, LC = Value in n divisions/ n

In this case LC = 0.05v and the pointer (n) is at 15th division.

Therefore, the observed reading of the voltmeter = 0.05 X 15 = 0.75 volts.

Explanation:

Least count can be defined as the least value the device can measure.

Here it is given that least count of the voltmeter is 0.05v

So,the reading of voltmeter =least count × the division

0.05 × 15=0.75v

Answer 2

0.75 volts....

Hope you understand. :)
