Ammeter is a low resistance galvanometer
It is used to measure the current in a circuit in amperes
Galvanometer can be converted into an ammeter by using a low resistance wire in parallel with the galvanometer
the resistance of the wire depends upon the range of the ammeter
As shunt resistance is small the combined resistance of the galvanometer & the shunt is very low hence the ammeter has much lower resistance than galvanometer
An ideal ammeter has zero resistance
It is the most common instrument used to measure voltage
It measure either AC or DC voltage
It is a measure of the voltage between two points of an electrical current
