how does a shunt help in converting galvanometer into ammeter?

OpenStudy (anonymous):

attach the shunt in parallel

OpenStudy (anonymous):

When the shunt is connected in parallel it will take more current as it has small resistance then does it not hamper in measuring the actual current?

OpenStudy (anonymous):

no no it wont hamper

OpenStudy (anonymous):

If not then why?kindly reply

OpenStudy (anonymous):

Since Galvanometer is a very sensitive instrument therefore it can’t measure heavy currents. In order to convert a Galvanometer into an Ammeter, a very low resistance known as "shunt" resistance is connected in parallel to Galvanometer. Value of shunt is so adjusted that most of the current passes through the shunt. In this way a Galvanometer is converted into Ammeter and can measure heavy currents without fully deflected

OpenStudy (anonymous):

Is the word shunt only used with low resistance or it represents any resistance altering the actual path of the current?

OpenStudy (anonymous):

shunt is the low resistance which alters the path of current

OpenStudy (anonymous):

Well shunt can represent a high resistance as in when we use it to convert galvanometer to ammeter,we put high resistance in series

true i forgot the point sorry
