Define ammemeter and voltmeter. Mention its uses.
Answers
Ammemeter, instrument for measuring either direct or alternating 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. ammeter.
A Voltmeter is an instrument used for measuring electric potential difference between two points in an electric circuit. Meters using amplifiers can measure tiny voltages of microvolts or less. Digital voltmeters give a numerical display of voltage by use of an analog-to-digital converter.
