Question

how will u connect ammeter in a circuit and write the method used to find the least count of an ammeter??

Answer 1

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 instrumentLeast count Formula:= value measured in n divisions/nLeast count of ammeter:The smallest value of current that can be measured For example: Let us calculate Least count of ammeter- 0-300mALeast count=range of ammeter divided by the number of divisionRefer attachment 1: for ammeter pictureSmall divisions=30suppose there are 30 division then, least count is=300/30=10mALeast count of Voltmeter:For example, let us calculate least count of Voltmeter 0-15volts.Please refer to Attachment2 for voltmeter pictureMain division 15subdivision 30least count=15/30=1/2=0.5Least count  of this voltmeter is 0.5

HOPE IT HELPS.........
IF MARK ME BRAINLIEST......

Answer 2

Ammeter is to be connected in series.
Least count = total range / total count
