Working Principle of Multimeter: A multimeter is basically a PMMC meter. To measure dc current the meter acts as an ammeter with a low series resistance. Range changing is accomplished…
Multirange Ohmmeter: The Multirange Ohmmeter circuit shown in Fig. 4.28 (a) is only for a single range of resistance measurement. To measure resistance over a wide range of values, we…
AC Voltmeter using Rectifiers: AC Voltmeter using Rectifiers - Rectifier type instruments generally use a PMMC movement along with a rectifier arrangement. Silicon diodes are preferred because of their low…
Chopper type DC Amplifier Voltmeter (Microvoltmeter): Chopper type DC Amplifier Voltmeter the dc input voltage is converted into an ac voltage, amplified by an ac amplifier and then converted back…
DC Ammeter: DC Ammeter - The PMMC galvanometer constitutes the basic movement of a dc ammeter. Since the coil winding of a basic movement is small and light, it can…
Classification of Printers: Classification of Printers - Character printers and graphic plotters are the two devices used to prepare a permanent (or hard copy) record of computer output. The basic…
Digital Display System: Digital Display System - The rapid growth of electronic handling of numerical data has bought with it a great demand for simple systems to display the data…
