``` . The term "ammeter" is sometimes used incorrectly as "ampmeter". Hence. From Ohm’s law, we will easily know that the current will be 1 Ampere. For example, let us use a simple electric circuit below. An ammeter (A) is placed in series to measure current. Just as you learned in basic electronics, more current will flow through a lesser resistance branch. What is an Ampere? You must have used these tools, not one or two of them, but all of them. The “0.5-Ω resistance” ammeter will make the current goes down to 10/2.5 = 4 A. Just like a voltmeter but we use the letter ‘A’ instead. The ideal ammeter has zero internal resistance. The other difference is the galvanometer is only capable of measuring DC. Its indicator pointer is moved by an armature, placed in the center of the magnet (similar to the simple dc motors). You should connect the … What we are supposed to understand here are: If you are reading this post I bet you have understood what is current. Be warned: an ammeter connected in series or connected in parallel with a electrical circuit will probably blow the fuse, which can possibly damage the ammeter and cause injury. The iron jaws of the meter direct the magnetic field surrounding the conductor to an iron vane that is attached to the needle of the meter. What is the difference between a multimeter, a voltmeter, an ammeter, and an ohmmeter? Don’t forget to connect the ammeter in series with the circuit. Since it is a “parallel” connection, we may call it a shunt resistance. Electrical currents are then measured in the form of amperes, hence the name, "ammeter". The electric current has the SI unit of Ampere, hence its measuring tool is named Amperemeter or simply Ammeter. Definition: The meter uses for measuring the current is known as the ammeter. The Columbia tong test ammeter (illustrated) is an example of the iron vane type, used for measuring large AC currents up to 1000 amperes. A voltmeter is connected in parallel with a device to measure its voltage, while an ammeter is connected in series with a device to measure its current. the circuit become: Like what you have noticed, the i1 is 0.19998 A.It is very close to the 2 A if we use Ohm’s law.
