 Why is ammeter connected in series?

Dear Student,

An ammeter is a low resistance device that is used to measure current flowing thorough a circuit. It is connected in series with the circuit, and as the resistance of an ammeter is very small, the voltage drop across the ammeter is negligible. When current flows through the ammeter, it is measured by the calibrated scale of the ammeter.

If the ammeter is connected in parallel with a circuit, it will lead to a short-circuit, because resistance of an ammeter is very low. Also the ammeter will be damaged.

Hope this answers your question,

Cheers!!

An ammeter by its nature has a very low input resistance. That is why if it is connected in parallel with a circuit element such as a resistor or a capacitor, it is the same as placing a very low resistor in parallel with the component or components across which is paralleled.

all this is Non Sense, all of them says that ammeter is a low resistance device but if you increase the resistance of the ammeter then can u join it in parallel????

If u want the real answer then take it form me

In reality, ammeter is the device which measure the amount of current passing through any cross section area of the conductor,

 u can compare it like the amount of person entering or exiting from the room, so if u want to count the number of person entering or exiting then u have to keep the gatekeeper at the door only, not at any other place.

similarly if u want to calculate the amount of current passing through any cross section then u have to place the ammeter in series only.

By chance if you kept it in parallel then also, it can calculate the amount of current that passes through that branch of circuit in which it is connected, not to other branch.

thats all

if u have any query then call me on 9913222254
