PARALLEL-SERIES DIGITAL VOLTMETERPETRENKO LEV P,SU
A voltmeter is connected in parallel with a load or with a source of electrical energy (Figure 1). The world’s first voltmeter was the “electric force indicator” of the Russian physicist G. V. Rikhman (1745). The operating principle of the “indicator” is also used in the modern ...
Explain why a voltmeter must be connected in parallel with the circuit. Draw a diagram showing an ammeter correctly connected in a circuit. Describe how a galvanometer can be used as either a voltmeter or an ammeter. Find the resistance that must be placed in series with a galvanometer to ...
Loading-Effects Reduction Using a Voltmeter in Series and an Ammeter in Parallel This article proposes a method for reducing the loading effects when a dc voltage or current is measured in a linear circuit with a digital multimeter (DMM... F Reverter - 《IEEE Transactions on Instrumentation &...
Such complex circuits may be made up of one or more branches in combinations of series and series-parallel arrangements. Britannica Quiz Electricity: Short Circuits & Direct Currents This article was most recently revised and updated by Erik Gregersen....
for measuring the DC voltages ofmultiple ranges, then we have to use multiple parallel multiplier resistors instead of single multiplier resistor and this entire combination of resistors is in series with the PMMC galvanometer. Thecircuit diagramof multi range DC voltmeter is shown in below figure....
or current is impressed on the circuit as a whole. We have examined the design of a simple voltmeter here. Ammeters follow the same general rule, except that parallel-connected “shunt” resistors are used to create acurrent dividercircuit as opposed to the series-connectedvoltage divider“...
