How we can convert moving coil galvanometer into an ammeter?

We can convert a galvanometer to an ammeter by connecting the galvanometer in parallel to a low resistance, which is known as a shunt. The value of the shunt is adjusted so that the maximum current flow through the shunt.

How will you convert a moving coil into an ammeter reading?

To convert a moving coil galvanometer to an ammeter, we add a low shunt resistance, but why? The shunt resistance carries the excess current, ensuring the right amount of current through the galvanometer.

How can a moving coil galvanometer is converted in to a voltmeter?

To convert a moving coil galvanometer into voltmeter, a high resistance is connected with it in series. A high resistance is connected in series with a coil of galvanometer to convert into voltmeter. A voltmeter is connected in parallel to the circuit because of its high resistance.

How will you convert moving coil galvanometer into ammeter resistance of ammeter is more or galvanometer Justify your answer mathematically?

A moving-coil galvanometer can be converted into an ammeter by reducing its effective resistance by connecting a parallel low resistance S across the coil. Such a parallel low resistance is called a shunt since it shunts a part of the current around the coil.

How can we convert a galvanometer into an ammeter and voltmeter?

A galvanometer can be converted into ammeter by connecting a low resistance called shunt in parallel to the galvanometer. A voltmeter is a device used to measure the potential difference between two points in a circuit.

How do you make an ammeter out of a galvanometer?

Galvanometer to an Ammeter A galvanometer is converted into an ammeter by connecting a low resistance in parallel with the galvanometer. This low resistance is called shunt resistance S. The scale is now calibrated in ampere and the range of ammeter depends on the values of the shunt resistance.

How a moving coil galvanometer converted into a voltmeter explain giving the necessary circuit diagram and the required mathematical relation used?

To convert a Galvanometer into voltmeter, a high resistance \((R)\) is connected in series with the galvanometer. Total effective resistance \(=(G + R)\). If \(V\) is the potential difference to be measured and if galvanometer gives full-scale deflection when current \(i_g\) passes through it.

How can we convert galvanometer into ammeter explain with suitable mathematical treatment?

A galvanometer can be converted into ammeter by connecting a low resistance called shunt in parallel to the galvanometer. Let G be the resistance of the galvanometer, I be the maximum current to be measured by the ammeter, and Ig be the maximum current that can be passed through the galvanometer.

How will you convert moving coil galvanometer?

EXPLANATION: A moving coil galvanometer can be converted into a ammeter by connecting a low resistance in in parallel to the moving coil galvanometer.

How can we convert ammeter into voltmeter?

Converting an ammeter to a voltmeter involves increasing the resistance of the ammeter. This is done by adding a high resistance in series with the ammeter. Let the range of the ammeter be 0 – I0 Amp and we convert it to a voltmeter of range 0 – V0 volt.

How do you convert a galvanometer to a voltmeter?

So a moving coil galvanometer is converted into an ammeter by connecting a very low shunt resistance in parallel to the galvanometer resistance. A good voltmeter has very high resistance. So a moving coil galvanometer is converted into a voltmeter by connecting a high resistance in series with the galvanometer resistance.

How to use a moving coil meter as a voltmeter?

To use the moving coil meter as a voltmeter, it needs a resistor in series with it called a multiplier resistor. The required resistor value is calculated from Ohm’s law. This is shown in Figure 1.

How to use a MCG as a voltmeter?

To use a M.C.G as a voltmeter, its resistance should be increased to a desired value and an arrangement should be provided to measure large potential difference. This is b.

How is water flow measured using a galvanometer?

The energy/push given for the water supply is the potential difference and the measure of the same is done by a voltmeter. If the waterfalls in minute drops (small electric current), then this water flow is measured by a galvanometer. The conversion of galvanometer into voltmeter is done by adding a highly-resistive multiplier in series.
