Ammeters must be connected in series with the load. When connecting in parallel the meter appears as a short. If you open the meter, there's usually an 850ma fuse, and/or a 2A and 10A fuse that you can replace and fix the meter.
Ohms, Volts, Inductance, Capacitance, Frequency, etc are all measured in Parallel, Only amps are measured in series. This is why there's always a separate "red" terminal for amps that you have to switch the lead to, so you know to connect it in series.
If you're trying to measure the ampacity of something, E.G. "How many amps does this power supply put out? You'll need to rig up a load in series with the meter, large variable resistors which are carbon piles are commonly used to test the condition of automotive batteries and vehicle charging systems (alternators).
An ammeter is always connected in series and a vlotmeter in parallel
Connecting an ammeter in parallel subjects that ammeter to the full supply voltage. The shunt resistor is not designed to sustain that value of voltage and will burn out. Also, the clue is in the word 'shunt' (which means 'in parallel') which means that the coil will also burn out!
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.
in voltmeter we have internal Resistance and connected in series , to current don't transfer in voltmeter , and we have internal resistance in ammeter and connected in parallel , to most current transfer through the ammeter.
For protection.. Since the current prefer the short cut ..
An ammeter is always connected in series and a vlotmeter in parallel
Because the ammeter connected in parallel will act as a short circuit.
Ammeter is coneccted in series with circuit but Voltmeter is connected in parallel.
An ammeter is connected in series. A voltmeter is connected in parallel. ammeter should always be connected in series instead of parallel becoz it is a low resistance device and we know that resistance is inversly proportional to current so more current will pass through it and if it is connected in parallel than it may get damaged

A shunt is connected in parallel with an ammeter. Any current applied to parallel devices will divide betwen them, so the ammeter will pass only a part of the total current.

By attaching a resistance in parallel connection with the galvanometer. Or when a low resistor connected in parallel with galvanometer ,the galvanometer is converted in ammeter. and the resistor is called shunt resistance.

Connecting an ammeter in parallel with a circuit element is hazardous. Because of its negligible resistance, it is equivalent to applying a short circuit across that element, and the resulting current through the ammeter may severely damage the instrument if it is not fused.
