How to use ammeter and voltmeter pdf

However, the voltage across the ammeter is the voltage across the galvanometer, typically 50 mV for the full-scale arrow deflection. If this voltage significantly disturbs the circuit in question, you would need an ammeter with a more sensitive galvanometer. × V[voltmeter]. O hm’s law enables us to use a milliammeter as a voltmeter. Let us suppose that we have a moving – coil instrument which requires 5 milliamperes for full-scale deflection (f.s.d.). And let us suppose that the resistance of its coil, r, is 20 ohms. An ammeter measures current, a voltmeter measures the potential difference (voltage) between two points, and an ohmmeter measures resistance. A multimeter combines these functions and possibly some additional ones as well, into a single instrument. Even the simplest and cheapest types may include features which you are not likely to use.

And let us suppose that the resistance of its coil, r, is 20 ohms. Conversion of voltmeter to ammeter Since the internal resistance of a voltmeter is much greater than ammeter, for conversion to ammeter we need to decrease the voltmeter’s internal resistance by adding appropriate shunt i.e. resistance in parallel to the meter. Let the range of the voltmeter be 0 – V0 volt and we convert it to an ammeter of range 0 – I0 Amp. Expt Ampmeter & Voltmeter and Ohmmeter-English Version, Page 1 of 24 Experiment : Ammeter, Voltmeter, and Ohmmeter I. Purpose : Understanding the structure of the ammeter, voltmeter, and ohmmeter. Learning how to use those meters and using them to measure the current, voltage, and resistance of an electric circuit. II. An ammeter measures current, a voltmeter measures the potential difference (voltage) between two points, and an ohmmeter measures resistance. A multimeter combines these functions and possibly some additional ones as well, into a single instrument. Even the simplest and cheapest types may include features which you are not likely to use.1CM15 Practice 1: Use of the ohmmeter, Voltmeter and Ammeter in measurements of D.C.
