Question

How to find least count in physics chapter electricity

Answer 1

Heya...

Here's your answer.........

1. Connect Ammeter in series and voltmeter in parallel in an electrical circuit. Then Note down the readings in ammeter and voltmeter.

2.Least count is the smallest value that can be measured by the measuring instrument

Least count Formula:= value measured in n divisions/n

Least count of ammeter:

The smallest value of current that can be measured

For example:Let us calculate Least count of ammeter- 0-300mA

Least count=range of ammeter divided by number of division

Refer attachment 1:for ammeter picture

Small divisions=30

suppose there are 30 division then, least count is

=300/30=10mA

Least count of Voltmeter:

For example let us calculate  least count of Voltmeter 0-15volts.

Please refer to Attachment2 for voltmeter picture

Main division 15

sundivision 30

least count=15/30

=1/2=0.5

Least count  of this voltmeter is 0.5
