Hint: We will answer this question by first understanding what galvanometer is? After understanding about the galvanometer we will know where all it is used and then look at the symbol of the galvanometer with the help of the diagram.
Complete answer:
Let us look at what a galvanometer is. Galvanometer is an electromechanical measuring device used to measure current flowing in the circuit. Let us look at the principle of galvanometer: it works on the principle that current- carrying coils placed in a magnetic field, experiences a torque.
The galvanometer has a needle which deflects when it comes in contact with the field. This device has been used in many ways:
-Experiments conducted in colleges use it for practical display.
-It can be used as both ammeter and voltmeter under certain conditions.
-It is used to find unknown resistance using wheatstone bridge
Let's look at the symbol of galvanometer:
There are 2 symbols for galvanometer:
-Here the alphabet G signifies galvanometer.
-Here the arrow mark signifies the needle present in the galvanometer.
There is no specific positive or negative side to it. But usually one side of the galvanometer is connected to the jockey.
Note:The SI unit of the galvanometer is ampere per division (A/div). It is a very sensitive device. It can be converted into an ammeter by connecting a low resistance device called shunt parallel to it. It can be converted to a voltmeter by connecting a resistance in series with it.
