Question

What is the least count
What is the reading on the voltmeter
If this voltmeter is connected to a 20 ohm resistor find the currrent flowing through it

Answer 1

Hey mate your answer is....

1... Least count of voltmetere = no. Of first

reading /total number of divisions

= 1.5 / 10

= 0.15 V

2.... Reading on volt meter = number of division × least count

= 12 × 0.15

=1.8 v

3....... To find current...

Given..

P. D = 1.8 v

R = 20 ohm

By ohms law

V = I × r

V /r = I

1.8 / 20 = r

0.09 A = I
