Question

stuck on experiment question-galvanometer resistance

Answer 1

1) how is the sensitivity of the galvanometer circuit used in this experiment changed when the shunt resistance is left connected?

2) explain why R_s=R_g? hint: it's a parallel circuit.
R_g: resistance of galvanometer

Answer 3

ok, it says in step 3 what you wrote...how I is same and then R_s=R_g

Answer 4

Yea i think so.

Answer 5

idk still doesn't explain WHY
