Electrical Measuring Instruments and its Electrical types

INTRODUCTION :- for the detection or measurement of electric current potential difference, and resistance certain instruments have been devised viz the galvanometer for the detection of small currents or measurements of small currents of the order of micro amperes or millionaires the voltmeter of potentiate for the measurements of potential difference (or voltage) between two points of a cur-cit or the emf of a source the ammeter for the measurements of large currents the Wheatstone bridge the meter Read more [...]
