Question

 If the resistance of the galvanometer is 40 Ω and a high resistance of 2000 Ω is connected in series with it to convert into voltmeter, then the net resistance of voltmeter is please answer​

Answer 1

• R_1=40ohm
• R_2=2000ohm

They are connected in series

$\boxed{\sf R_{eq}=R_1+R_2}$

$\\ \sf\longmapsto R_{eq}=40+2000$

$\\ \sf\longmapsto R_{eq}=2040\Omega$
