why we convert a galvanometer into voltmeter and ammeter?

TVP45 said:So you can measure voltage and current.

A galvanometer is a device used to measure small electrical currents. By converting it into a voltmeter, we can measure the voltage of a circuit, which is a more useful and practical measurement for most applications.
A galvanometer is converted into a voltmeter by adding a high resistance in series with it. This resistance is known as a shunt resistor and it allows the galvanometer to measure larger currents without being damaged.
Similar to converting a galvanometer into a voltmeter, converting it into an ammeter allows us to measure larger currents. This is achieved by placing a low resistance in parallel with the galvanometer, known as a multiplier resistor.
The purpose of converting a galvanometer into a voltmeter and ammeter is to make it more versatile and suitable for different types of measurements. By adding resistance in series or parallel, we can change the range and sensitivity of the galvanometer to measure different quantities.
No, a galvanometer cannot be used as a voltmeter or ammeter without converting it. This is because it is designed to measure small currents and does not have the necessary resistance to measure larger currents or voltage. Converting it with the appropriate resistors allows it to be used as a voltmeter or ammeter.
