Ammeter
Product Code : EL-LM-10383
Quick answer: The Ammeter is an analog moving-coil instrument for measuring the electric current in a laboratory circuit, read in amperes. It stands on a Bakelite or acrylic base with lock-type terminals, is accurate to ±2% F.S.D. and is available in all common ranges. Lab Exports manufactures it in Delhi for schools, colleges and universities.

How the ammeter is used
An ammeter measures the current flowing through a circuit, so it must be connected in series: the circuit is broken and the meter inserted in the gap. A good ammeter has a very low resistance so that adding it barely changes the current it is measuring. In the moving-coil type the pointer deflection is proportional to current, giving an evenly divided scale that is easy for students to read.
- Choose a range larger than the current expected; if unsure, start with the highest range.
- Switch off the supply and break the circuit at the point where current is to be measured.
- Connect the ammeter in series, with its positive terminal towards the positive side of the supply.
- Switch on, read the pointer against the scale, and switch off before changing connections.
Ammeters are used throughout school and college electricity work: Ohm's law, resistances in series and parallel, the heating effect of current, and the characteristics of diodes and lamps.

Frequently asked questions
How is an ammeter connected in a circuit?
In series, so that the whole current being measured passes through it. Connecting an ammeter directly across a supply can damage it.
What is the accuracy of the ammeter?
±2% of full-scale deflection.
