If ammeter 1 reads 2.A what will ammeter 2 read?
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.
Why is ammeter connected in series?
to read the amperage
What happen if you change the position of ammeter in the circuit in parallel and series?
-- In a series circuit, no matter where you install the ammeter, it will always read the same current. -- In a parallel circuit, the ammeter may read a different current when it's moved to a different parallel branch.
What is a galvanometer called when calibrated to read current?
That would be an ammeter.
Why is it important to connect the positive lead of the ammeter to the positive side of the battery?
The ammeter will only read when connected properly. If the meter is connected backwards, then the meter reads the wrong way. If it is a digital ammeter then it may not work at all.
Unit used to measure the magnitude of current?
Ammeter. Will read in Amps or milliamps.
What will an ammeter show if the circuit is broken?
Zero. No current is flowing in an open circuit. The ammeter will display an amount of 0 amps because there is no longer any current once the circuit has been broken. An ammeter measures current.
What does the reading on a ammeter say when the switch is open?
An open switch in a circuit will stop all current flow so the ammeter should read zero amps.
How would you connect an ammeter if you want to measure the current coming through some device in a 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.
How do you calculate the ammeter reading?
The voltage remains the same across the circuit as it is a parallel connection. So, the current across the upper half of the circuit where the ammeter is connected is calculated as I = V/R = 12.04 (total voltage)/12 (Resistance R1) = 1 A. Hence, the ammeter will read 1 A.
How is an ammeter converted to a voltmeter?
The ammeter is used in series, because you want to measure the current through a circuit. The voltmeter is used in parallel, because you want to measure the voltage across a circuit. If you were to place the voltmeter in series, no current would flow because of the relatively high impedance of the voltmeter. If you were to place the ammeter in parallel, you would create a short-circuit, due to the relatively low impedance of the ammeter.
What would happen if a voltmeter were substituted for an ammeter?
Smoke. Since a voltmeter is in parallel with the load it is right across the source voltage. Putting the amp meter across the line with its low resistance it will act like a fuse, hence the smoke. Newer solid state testers are usually smarter that the operators. They have built in circuitry which sense the wrong settings you are using and shut the tester off with a "beep" to let you know that you are doing something wrong.
