Ampere meter is a device used to measure the electric current, which is modified from the resistance, with ค่าน้อยๆ Come on stream flow parallel to break from the Gallery Gallery AE meter too weak meter down
.When we want to measure the very valuable, do as follows:
1. The resistance to parallel with galleries AE meter
2. Resistance must be worth little. So the flow resistance. In order to reduce the current to flow through the meter Gallery AE
.The properties of good
1 ammeter.High accuracy, which caused little resistance to that when the ammeter to ในวงจร series and will not make collective resistance circuit change make current measured high accuracy or faults from less measurement
.2.High sensitivity, low resistance when the current flowing through the will be very valuable to the current flowing through the gallery แอมิ factor is less that is good ammeter can measure the current value that is even less circuit is less current ammeter.Can be measured by
