Can a galvanometer be converted into ammeter Class 10?

Can a galvanometer be converted into ammeter Class 10?

An ammeter is made from a galvanometer. Or we can also say that a galvanometer can be converted into an ammeter. To convert a galvanometer into an ammeter, we connect a resistance R parallel to the galvanometer. This resistance is called shunt resistance.

How can you convert a galvanometer into an ammeter explain with diagram?

A galvanometer can be converted into an ammeter by connecting a low resistance in parallel with it. Here Galvanometer and shunt resistances are connected in parallel.

How can a galvanometer can be converted into voltmeter?

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 be converted into an ammeter by connecting?

The correct answer is A low resistance in parallel. Explanation: We can convert a Galvanometer into an ammeter by connecting a low resistance in parallel. A device that is used to measure electric current in a circuit is called an ammeter.

Why do we use a shunt to convert a galvanometer into an ammeter?

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 we can convert a galvanometer into ammeter and voltmeter along with their expression?

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 can galvanometer be converted into ammeter and voltmeter?

An ideal ammeter has zero resistance. Galvanometer can be converted into ammeter by shunting it with a very small resistance. Potential differences across the galvanometer and shunt resistance are equal. Galvanometer can be converted into voltmeter by connecting with it with a very high resistance.

Why do we convert galvanometer into voltmeter?

Voltmeter is always connected in parallel to a circuit. Since Galvanometer is a very sensitive instrument, therefore it can not measure high potential difference. In order to convert a Galvanometer into voltmeter, a very high resistance known as “series resistance” is connected in series with the galvanometer.

How is ammeter connected in a circuit?

Key Points An ammeter is a measuring device used to measure the electric current in a circuit. A voltmeter is connected in parallel with a device to measure its voltage, while an ammeter is connected in series with a device to measure its current.

How can we convert galvanometer into voltmeter and ammeter?

1 Answer

1. A galvanometer is converted into a voltmeter by connecting a high resistance ‘R’ in series with it.
2. A galvanometer is converted into an ammeter by connecting a small resistance (called shunt) in parallel with it.
3. Resistance of voltmeter, RV = G + R.

When galvanometer is converted into ammeter the resistance connected is?

A galvanometer is converted into an ammeter when we connect a low resistance in parallel. 2. A galvanometer is converted into a voltmeter when we connect a high resistance in series.

How is a galvanometer converted into an ammeter Mcq?

Explanation: A galvanometer is converted to an ammeter by connecting a low resistance in parallel so that only a safe fraction of the current passes through the ammeter.

How is ammeter and voltmeter connected in a circuit and why?

There is a difference between the ways in which, a voltmeter and an ammeter are connected in a circuit. When measuring the voltage across a resistor or a conductor element, the voltmeter is always connected in parallel. As opposed to this, to measure the current flowing through a circuit element, an ammeter should be connected in series.

How is the ammeter used in a circuit?

– Most ammeters use color coding to indicate positive and negative ends of a circuit. – The most commonly used ammeters have clamps that allow them to easily attach to wires. – You can also simply hold the leads of your ammeter to the bare wires of the broken circuit. – Be sure to only test one wire at a time.

What is a standard voltmeter and a standard ammeter?

A voltmeter is designed to measure the voltage across a portion of a circuit, while an ammeter is designed to measure the current passing through a particular point in the circuit. That is, the voltmeter stays outside the circuit, while the ammeter must be inserted into the circuit. While these devices have

How should ammeter and voltmeters be connected in a circuit?

An ammeter is a measuring device used to measure the electric current in a circuit. A voltmeter is connected in parallel with a device to measure its voltage, while an ammeter is connected in series with a device to measure its current.
