Answer:
answere is 9980 ohms
Explanation:
As we know that converting a galvanometer into voltmeter,we use formula
Rh=V/Ig -Rg
where Rh is the series resistance
V is the voltage
Ig is full scale deflection
Rg is resistance of galvanometer
so by putting values:
Rh=10/0.001 -20
Rh=9980 OHMS.
I hope it will help you all.
