Because in ammeter current range we want to increase. So when Shunt is connected some current will also pass through it. So shunt in Ammeter. Also in Voltmeter we know voltage is not same in series so some voltage drop happen across the series resistance also. So total voltage measuring increases
Y didn't you use
I= Im + Ish , when looking for Ish
Madam I need a topics on auto ranging auto zeroing and automatic polarity indication..
Thank u
Thank you ma'am
Most welcome 😊
Why there is shunt resistance in ammeter and series resistance in voltmeter?
