Current "flows" through the circuit, through the conductor. Hence an ammeter is in series so that the current under measurement also flow through the meter and measured.
Ammeters must always be placed in series in a circuit, otherwise they will not work babes :)
Ammeters are added in series to the circuit to be monitored.
Scientists use ammeters to measure the flow of electric current in a circuit. Ammeters are connected in series to the circuit and provide a precise measurement of current in amperes, helping scientists analyze how electricity is behaving within a system.
Ammeters measure the current flowing through a circuit
If an ammeter is placed in parallel with a a load on a circuit, the circuit can short out as the ammeter takes the place of the load, flowing freely through the meter. Never measure across a resister or other electronic load with an ammeter. Remember, ammeters are used in series while voltmeters are used in parallel.
Ammeters are connected in series with the load under test. This requires the load be disconnected from the source, and the ammeter placed in circuit. Voltmeters are connected in parallel with the load under test. This does not require any circuit changes. Sorry, but WikiAnswers does not support illustrations.
Series. An ammeter is used to measure current, and is connected in series! There are also clamp on ammeters that use a small current transformer that is placed around a wire in the current loop in question. A small amount of current will be induced on this wire which can be read by the meter. This is not exactly in series or in parallel, but it "steals" some power from the circuit to induce in the meter, and at the same time keeps the circuit intact.
series circuit
Because ammeters have low resistance. If you connected them in parallel, all the current would flow through the ammeter instead of the circuit you were trying to test, possibly frying the meter but certainly invalidating the measurement.
To measure the amount of amps (A).
Connect ammeter in series and voltmeter in parallel to the circuit
Current is the amount of electrons flowing. An ammeter reads this value. Typically an ammeter will be placed in series to measure this flow; there are also "clamp on" ammeters that use a small CT. When placed around a wire, the power flowing in the wire will induce a current in the CT, allowing measuremnt without lifting wires.
