An ammeter is a amp meter put into a circuit in series. There is virtually no voltage drop or resistance in an ammeter so two in series would be redundant. If you have one in a circuit it will tell you the amps that circuit is generating, two would both give virtually the same result.
What else can I help you with?
When measuring with an ammeter the ammeter must be connected in?
When measuring a load current, an ammeter is connected in series with the load. The exception is for a clamp on style AC ammeter, which is clamped around one of the conductors, making its measurements as a transformer.
Why is an ammeter is always connected in series with the circuit?
When considering electricity, Current (measured in Amps) is often considered the flow of energy. The force behind the flow is the Volts. While the volts can be measured between any two points in the circuit (open, or closed), measuring the current, or flow of energy typically requires interrupting the flow. Somewhat like water. One can measure pressure of the water on a branch, but one must have a way to monitor the actual flow to determine how much water has passed. There are "exceptions" though. If you have an AC circuit, then an inductive ammeter can measure the amps around a single leg if the circuit without being installed inline with the circuit. Even with a DC circuit, it may be desirable to design a bypass or shunt circuit so that the majority of the current bypasses the ammeter, and only a small amount of the current actually flows through the ammeter.
How can you connect current transformer to ammeter in three phase?
You use three CTs, one per line conductor, each feeding a separate ammeter,
What circuit only has one loop?
A Series circuit
What components do you need to make a simple series circuit to light on bulb?
You need a Battery, Light Bulb, Ammeter, Switch.
What is ammeter used for?
An ammeter measures the electrical current in something. A digital one is calibrated to display through the shunt and convert information from the analog model.
How is an ammeter connected in a circuit?
Series connect it within the line of the circuit for which you are interested in measuring the current flow.More detailSince we measure the flow of current IN the circuit, the ammeter must be connected in series with the part of the circuit for which you are interested in measuring the current flow.One of the ammeter's terminals must be connected to a point of the incoming current flow and its second terminal must be connected to the point of on-going current flow. To do this, cut the relevant circuit wire and connect one terminal of the ammeter to each end of the cut.
Where ammeter and voltmeter are put in circuit?
Place in parallel anywhere in the circuit. One lead goes to the hot, the other to the neutral.

How do you measure the current through a circuit without intercepting the supply?
Add an ammeter in parralel with the circuit. An ammeter in parallel with a circuit to be measured will not measure any current. In fact, placing an ammeter in parallel will cause a short. The ammeter must be placed in series with the circuit to be measured. It should be noted that this technique only allows for small magnitudes of current to be measured. One should not try to measure more than 10 amps using this method. However, this is not the goal of the question asked. I am not 100% sure what "intercepting the supply" means but I think the person asking the question means without breaking the circuit? In this case one could use a clamp on ammeter. There are several varieties that can measure low currents and there are those that can measure 100s of amps.

What is the effect caused by ammeter resistance when an ammeter is inserted into a circuit to measure the current?
The effect the multimeter might have on the circuit when inserted to measure the current is to increase the circuit resistance and decrease the available voltage to the circuit. This is because the multimeter in amps or milliamps mode does have a small resistance which is not zero, so by Ohm's law, there is a voltage drop across the multimeter; small, but not zero. Usually this effect is small. One way to compensate is to start by measuring voltage, and then inserting a separate ammeter and adjusting the power supply to match the original voltage. Of course, the voltmeter must be downstream of the ammeter.
When measuring current always place any type of meter in series with the circuit--is this true?
No. While it is true that one can measure current at any point in a circuit by breaking the circuit at that point and inserting the meter, not any meter will do it. One must use an ammeter to measure current.
Why is an ammeter also called a tell tale?
There are some applications where using an ammeter is the only way to troubleshoot a problem without tearing apart the entire circuit. It is the only meter setting on the DMM used while the circuit is energized. After calculating the amperage that should flow through the circuit by measuring ohms and volts, an ammeter directly shows any "tell tale" discrepancies between calculated amps and actual amps. Example: In theatre lighting, a volt meter reads 110V on a power circuit, and an ohmmeter reads close to 0 when measuring across a lamp's power connector leads; yet, when connected, the lamp won't light and the breaker doesn't trip. In theory, 110V across a lamp reading 0 ohms should light the lamp. A quick bit of minor surgury and a measure with the ammeter "tells the tale" that very little current is flowing; therefore, one of the digital dimmer packs has probably gone bad -- it will provide a phantom power of 110V with little current. Without the ammeter, one would have to waste time troubleshooting the dimmer itself.
How many amps are in 1 ampmeter?
One ampere (amp) is the unit of electric current and an ammeter is a device used to measure current. So, an ammeter measures the number of amperes flowing in a circuit, rather than containing a specific number of amps itself.
