Voltmeter #!#Ammeter

Short- Circuit OF Resistor-Battery or Combination||Galvanometer - Concept|| Voltmeter and Ammeter Basics

A battery of electro motive force E is connected in series with a resistance R and a voltmeter. An ammeter is connected in parallel with the battery.

A student connects a voltmeters, ammeter and resistance according to the circuit given. If the voltmeter reading is 20V and ammeter reading is 4A, then the resistance will be

What will be the reading in the voltmeter and ammeter of the circuit shown in fig.

If the positions of voltmeter and ammeter are interchanged in Ohm's law circuit, then

In the series L-C-R circuit , the voltmeter and ammeter readings are respectively

If x, y are the readings of voltmeter and ammeter in Sl units respectively then x + y =

In the circuit shown in figure neglecting source resistance the voltmeter and ammeter reading will respectively, will be

In the series L-C-R circuit , the voltmeter and ammeter readings are

In Fig. 6.61 the voltmetre and ammeter shows are ideal. Then voltmeter and ammeter readings, respectively, are
