Solve by difficulty

For what value of R will the current in galvanometer zero ?

 

In an experiment according to set up, when E1 = 12 volt and internal resistance zero, E = 2 volt. The galvanometer reads zero, then X would be

The deflection of a moving coil galvanometer falls from 60 div to 12 div when a shunt of 12 \Omega is connected.The resistance of the galvanometer is

The galvanometer Q has internal resistance \mathrm{Q=50\, \Omega} and full scale deflection occurs at \mathrm{i=1 \mathrm{~mA}}.Find the series resistor \mathrm{R_{3}} needed to use the arrangement as a voltmeter with different range as shown in the figure.  



 

Concepts Covered - 1

KCL, KVL, Conservation of charge and Energy and introduction to Galvanometer

KCL, KVL, Conservation of charge and Energy and introduction to Galvanometer-

KCL is simply based on conservation of charge. That is charge cannot accumulate at a junction. 

KVL is based on conservation of energy. That is energy supplied by the source will be equal to the energy consumed by the circuit elements

\sum V=0

 Galvanometer-

It is an instrument used to detect small current passing through it by showing deflection.

Example for types of galvanometers are

moving coil galvanometer

moving magnet galvanometer
