When an ammeter is shunted then its measuring range is?

When an ammeter is shunted then it provides the low resistance path. In order to increase the range of ammeter, the value of shunt resistance is decreased. When an ammeter is shunted then its measuring range will increase.

What is the range of an ammeter scale?

Range of the ammeter means the maximum capacity of current it reads. For example if you take an ammeter which has a dial 0 —300, it means it can read the current upto 300 amp.

How do you find the range of an ammeter?

The ammeter has to be set up in series and voltmeter in parallel. Take down the readings and get the graph between V and I. See the slope it will give you the resistance of the wire! The ranges of voltmeter and ammeter are already mentioned on them thus eliminating the need to calculate them.

What do you mean by range of ammeter?

The range of any meter, from ammeter in your lab to speedometer in a car, vary according to their use. The ammeters used in the college laboratory have range of (0–50) mA , (0–100) mA as high as (0–500) mA. The reason is simple, we do not work with current higher than this.

What is the effect of the current measuring range of a galvanometer when it is shunted?

Value of shunt is so adjusted that most of the current passes through the shunt. In this way a Galvanometer is converted into Ammeter and can measure heavy currents without fully deflected.

Which of the following is measured by Ammeter?

Answer: Ammeter, instrument for measuring either direct or alternating electric current, in amperes.

What is the range of the ammeter and the range of the voltmeter?

It is not possible to decrease the range of an ammeter. However, it can be increased by connecting a shunt (or low resistance) in parallel with the Ammeter. A voltmeter can have a maximum range of 0-20 V.

What is the meaning of range of ammeter and voltmeter?

A voltmeter is an instrument used for measuring electrical potential difference between two points in an electric circuit. An ammeter is a measuring device used to measure the electric current in a circuit.

How do you change the range of an ammeter?

So to increase the range of ammeters we should have to connect low resistance in parallel so that equivalent resistance is lower hence to increase range of an ammeter we need to connect a suitable low resistance in parallel.

What is the effect on the current measuring range of a galvanometer?

Since Galvanometer is a very sensitive instrument therefore it cant 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.

Which effect of current is used in galvanometer?

A galvanometer works by deflecting a pointer in response to an electric current flowing through a coil in a constant magnetic field.

What is measured by an ammeter Brainly?

Answer: The instrument used to measure the current is called an ammeter. Explanation: So, the instrument used to measure the flow of current in amperes is called the ammeter.
