Question

galvanometer is always connected in​

Answer 1

Answer:

• The act of measuring any electromagnetic field has a slight effect on the field itself. The charge it takes to create a rotary deflection of a pointer in a galvanometer may affect the final output.

• This effect can be effectively studied and counter-measures can be established by connecting galvanometers in a series. If the second galvanometer shows a different reading than the first, the difference can be used to calculate charge loss through metering and instrumentation

Hope it helps

Answer 2

Answer :

Ammeter

Explanation :

The deflection of the coil is directly proportional to the current flow through it.
