Questions
Resistance of a galvanometer coil is and permissible current through its coil is 10 mA. If can be converted into an ammeter of range 1A by connecting a resistance of
detailed solution
Correct option is D
The resistance R is to be connected in parallel combination with the galvanometer coil.∴ R1−10×10−3=100×10×10−3⇒R=1000×10−31−0.01Ω=1.01ΩTalk to our academic expert!
