Are Galvanometer and Ammeter the Same?

For electrical instruments, measurements of parameters like current flow are very important. ... The main difference between these two is that the galvanometer shows both the direction and the magnitude of the current. But, the ammeter only shows the magnitude of the current.

Does ammeter contain galvanometer?

Galvanometers as Ammeters

The same galvanometer can also function as an ammeter when it is placed in parallel with a small resistance R, often called the shunt resistance.

Why we Cannot use galvanometer as an ammeter?

A galvanometer shows a full scale deflection with a very small current. Hence a galvanometer can measure limited current. Therefore as such, a galvanometer can not be used as an ammeter, which can measure the given large current.
