(c)
(a)
i) A galvanometer can be convereted into an ammeter by connecting a wire of a
resistance with the galvanometer,
(a) in series
(b) In parallel
(c) in a combined way (d) In no way
tell me all question​

Answer 1

Answer:

1st answer is waves

2nd is When the electromagnetic theory is expressed in the International System of Units, force is measured in newtons, charge in coulombs, and distance in meters. Coulomb's constant is given by ke = 14πε0.

3rd is A galvanometer can be converted into a ammeter by connecting a shunt resistance in parallel to it.The shunt resistance should have a very low resistance .So, the ammeter (parallel combination of galvanometer and shunt resistance ) will have low resistance.
