# What would you look for in a good ammeter? ## Related Questions

If the voltmeter was ahead of the ammeter, the voltmeter would read supply voltage, and the ammeter would read current through the voltmeter, a very small reading. If the ammeter was ahead of the voltmeter, the ammeter would read supply current, which is probably many times in excess of the ammeter's rating, so you would either destroy the ammeter (or battery) or blow its fuse. It does not matter about the voltmeter, as the ammeter is now blown.

An ammeter is always connected in series in the circuit.

The ammeter would be destroyed by excessive current but nothing would happen to the voltmeter

On a schematic diagram, an ammeter is typically represented by a circle with the letterAinside the circle.

Impossible to answer with the information given. A good start would be to look at what the power supply is rated for. The only sure fire method to test this is with a clamp-on ammeter.

To increase the range of an ammeter, you connect a very low impedance resistor in parallel with the ammeter.

Connect ammeter in series and voltmeter in parallel to the circuit

HOW TO CONNECT AN AMMETER Always connect an ammeter in SERIES in a circuit. Always ensure that the ammeter has a higher reading range than the expected current load, including start-up spikes. An ammeter expected to read a steady current of 13A should have a max range of 20A.

If an ammeter read 2A, another ammeter would probably also read 2A. Keep in mind that every measurement involves error, and the equipment has a stated accuracy. If, for instance, the ammeter used had a 1% tolerance, than 2A actually means anywhere between 1.98A and 2.02A.

The positive terminal of the battery would be connected to the positive terminal of the ammeter. The load would then be connected between the two negative terminals, positive side of the load being connected to the negative side of the ammeter.

The term ammeter is a contraction of ampere meter, which is what the ammeter does - it measures amperes.

a dc ammeter is a ammeter which has three pins and it works by two wires.

All the current would go through the ammeter. The whole purpose for making a measurement with an ammeter is to determine current draw through a component or circuit. If the ammeter takes all the current away from the device under test, the reading would be meaningless. Also, since the ammeter would present pretty much a dead short to the power supply, blown fuses or toasted components usually result.

An ammeter has a finite resistance which is inserted in series with the rest of the circuit, increasing the total resistance and decreasing the current. A good ammeter has a very low resistance, so it shouldn't affect the circuit noticeably.

if we take resistance in parallel with ammeter then the range of ammeter will change.

Look good to whom? To me? No. What's to look good? Wounds? Why would wounds look good? If attention is what you want, there are many positive ways to get good positive attention.

the internel resistense of ammeter is as maximum as possible. for ideal ammeter it is infinite

An ammeter can be converted into a voltmeter by connecting a resistor in series with it. This works best if the ammeter is a very sensitive ammeter, such as in the micro ampere range. More commonly, a voltmeter (or sensitive ammeter) is converted into an ammeter by placing a small resistor in parallel with it.

Ammeter sensitivity can be determined by a change of scale for the ammeter which would introduce higher or lower resistance values depending on the reading required. A higher sensitivity for lower values of ampacity would require higher resistance in the measuring circuitry. Use Ohm's law to verify.
