Ohmmeter : Basic Concept, Working principle, Types and Uses

WebAmmeters were laboratory instruments that depended on the earth’s magnetic field for operation. In the 19th century, the ammeter with the ability of accurate measurements, which could be mounted in any position was invented. Ammeter is a device used to measure either alternating or direct current. We know that ampere is the unit of current. WebThe scale of the PMMC instrument can be calibrated to read the current passing through the heater. This is the basic thermocouple instrument working principle. These instruments can be used for both AC as well as DC applications. These instruments are very useful and accurate to measure current and voltages at very high frequencies. Webammeter, instrument for measuring either direct (DC) or alternating (AC) electric current, in amperes. An ammeter can measure a wide range of current values because at high values only a small portion of the current is directed through the meter mechanism; a shunt in parallel with the meter carries the major portion.
