Which terminal of ammeter is connected to battery?
Why is it important to connect the positive lead of the ammeter to the positive side of the battery? How does the ammeter affect the flow of current? The ammeter does affect the flow of current in a circuit, however, the resistance of the ammeter is so small in comparison to the circuit that the effect is negligible. It is connected in series.

Ammeter
Ammeter from the old New York Penn Station terminal service plant in New York City. The relation between electric current, magnetic fields and physical forces was first noted by Hans Christian Ørsted in 1820, who observed a compass needle was deflected from pointing North when a current flowed in an adjacent wire. The tangent galvanometer was used to measure

It is just a labelling convention which will give you a positive reading on the ammeter if a current enters the ammeter at the red terminal and a negative reading if the current leaves the ammeter from the red terminal. With moving coil meters a current entering the positive terminal will deflect the needle/spot of light to the right.

Ammeter: Definition, Measures & Function
An ammeter must always be connected in series with the element in which the current is measured, as that''s when the current stays constant. An ideal ammeter has zero resistance, meaning it doesn''t affect the current in the element it''s in series with. The symbol for an ammeter in an electric circuit is the letter "A" confined within a circle.

How Can I Test My Ammeter?
Test the ammeter with the connections + from battery to + on meter and - battery to - meter and note the ammeter needle deflection. Reverse the connections on either the battery or the ammeter and you should have the same deflection the opposite way. Of course, at no current flow, the needle should read zero.

Why do cables and batteries have a positive and a negative side?
Electrons flow out one side (the negative one) and come back in from the other (the positive one). Current is not associated with electron accumulation, but with electron flow. The point of the battery is pushing electrons from the positive to the negative terminal: this pushing requires energy, that is chemically kept in the battery, used to push the electrons that then release it

Can a battery be shorted with an ammeter?
Testing a battery's current supply capability by shorting it with an ammeter is a very bad idea in many cases, and an effective but informal method in selected cases. For Alkaline and carbon zinc batteries in the AA size, short circuit current capability is usually inder 10 amps even when new.
Can I connect an ammeter in series with a battery?
I had the concept that in order to check the maximum current a battery can supply, it is fine to connect an ammeter in series with battery because ammeter has low resistance in series and this will yield the maximum current a battery can supply. Many people have said it is wrong, but I can't understand why.
What is the difference between a current meter and an ammeter?
Electric currents are measured in amperes (A), hence the name. For direct measurement, the ammeter is connected in series with the circuit in which the current is to be measured. An ammeter usually has low resistance so that it does not cause a significant voltage drop in the circuit being measured.
What does an ammeter measure?
An ammeter measures the electric current in a circuit. The name is derived from the name for the SI unit for electric current, amperes (A). In order for an ammeter to measure a device’s current, it must be connected in series to that device. This is necessary because objects in series experience the same current.
What is a Digital ammeter and how does it work?
A Digital ammeter measures current flow in amperes and displays the current levels of your battery. It is easier to read than old battery charge amp meters because it displays the reading and works quicker.
Why does an ammeter measure the current in a circuit?
An ammeter measures the current by having very low resistance, which allows the opposite electric current to flow through it and be measured. To measure the current in a circuit, you must connect an ammeter in series.
