Why do we convert galvanometer into ammeter and voltmeter?

A galvanometer is very sensitive instrument to detect the current. It can be easily converted into ammeter and voltmeter. A galvanometer is very sensitive instrument to detect the current. It can be easily converted into ammeter and voltmeter.

Why can’t we use ammeter instead of galvanometer?

A galvanometer shows a full scale deflection with a very small current. Hence a galvanometer can measure limited current. Therefore as such, a galvanometer can not be used as an ammeter, which can measure the given large current.

Why is it necessary to convert a galvanometer to voltmeter why not use a galvanometer directly instead?

Since Galvanometer is a very sensitive device. If a low value of current pass through the galvanometer, then it may burn of explode. Therefore, it is converted into voltmeter by connecting the coil of the galvanometer with a low resistance in parallel combination ammeter is made.

Why has an ammeter of very low resistance How can you convert a galvanometer into ammeter?

A galvanometer can be converted into ammeter by connecting a low resistance called shunt in parallel to the galvanometer. Since S is low resistance, resistance of ammeter RA is very low and when it is connected in series in the circuits, it will not affect the current passing through the circuit.

Why do we need a galvanometer?

A galvanometer is used for measuring or for detecting small currents. But by converting a galvanometer into an ammeter large currents can be detected. To convert a galvanometer into an ammeter, a low resistance known as shunt resistance is connected parallel to the galvanometer.

Why ammeter has a shunt resistance connected with galvanometer?

A shunt resistance should be connected in parallel to the galvanometer so as to keep its resistance low. Such low resistance galvanometer ( ammeter) is used in series with the circuit to measure the strength of current through the circuit.

Why is galvanometer used?

galvanometer, instrument for measuring a small electrical current or a function of the current by deflection of a moving coil. The deflection is a mechanical rotation derived from forces resulting from the current.

What is a galvanometer why it is used?

A galvanometer is an electromechanical measuring instrument for electric current. Early galvanometers were uncalibrated, but improved versions, called ammeters, were calibrated and could measure the flow of current more precisely. They were the first instruments used to detect and measure small amounts of current.

What is the use of converting galvanometer into voltmeter?

Galvanometers were the first instruments used to detect and measure electric currents. A galvanometer can be converted in to a voltmeter by connecting a high resistance in series connection within it. The scale is calibrated in volt. The value of the resistance connected in series decides the range of the voltmeter.

Can you use galvanometer instead of ammeter?

Solution: Yes, we can use a galvanometer as an ammeter in the circuit. We can convert it into an ammeter. For this conversion, a low resistance known as shunt resistance has to be connected in parallel to the galvanometer.

Why the resistance of galvanometer is low?

Since Galvanometer is a very sensitive instrument therefore it can’t measure heavy currents. In order to convert a Galvanometer into an Ammeter, a very low resistance known as “shunt” resistance is connected in parallel to Galvanometer. Value of shunt is so adjusted that most of the current passes through the shunt.

What is the use of galvanometer and ammeter?

A galvanometer can be turned into an ammeter by parallely connecting a resistance in the electric circuit. It can be used as a voltmeter when resistance is connected in series with it….
