Q. A galvanometer can be converted into an ammeter by connecting

KEAMKEAM 2009Current Electricity

Solution:

An ammeter is an instrument which is used to measure current in a circuit in ampere (or rnilli ampere or microampere).
Hence, it is aiways connected in series in the circuit
To convert a galvanometer into an ammeter its resistance is to be decreased, so to convert a galvanometer into ammeter a low resistance called shunt (S) is connected in parallel to the galvanometer.
