High resistance in parallel connected with galvanometer to form voltmeter?
That won't work. To convert an ammeter (a galvanometer is a very sensitive type of ammeter) you connect a high value resistor in series with it.
How is an ammeter converted to a voltmeter?
The ammeter is used in series, because you want to measure the current through a circuit. The voltmeter is used in parallel, because you want to measure the voltage across a circuit. If you were to place the voltmeter in series, no current would flow because of the relatively high impedance of the voltmeter. If you were to place the ammeter in parallel, you would create a short-circuit, due to the relatively low impedance of the ammeter.
What are the advantages of a moving iron ammeter?
The advantages of a moving iron ammeter is that it can accurate measure the amount of electricity which is flowing. This makes it well suited for both monitoring and controlling the amount of electricity in a circuit.
What is the Purpose of shunt in ammeter?
The purpose of a shunt in an ammeter is to allow the measurement of large currents without damaging the instrument. It does this by providing a low-resistance path for most of the current to flow through, while directing only a small, measurable fraction of that current through the ammeter itself. This enables the ammeter to accurately display high currents while protecting its internal components. By using a shunt, the design of the ammeter can remain compact and sensitive, suitable for a wider range of applications.
How does measure current with an ammeter connect the ammeter to what?
To measure current with an ammeter, it must be connected in series with the circuit component whose current is being measured. This ensures that the same current flowing through the component also flows through the ammeter, allowing it to accurately measure the current. The ammeter has a low resistance to minimize any impact on the circuit's operation. Proper connection is crucial to obtain accurate readings without disrupting the circuit's functionality.

Why is ammeter connected in series with the load?
An ammeter is connected in series with the load to measure the current flowing through the load. By placing the ammeter in series, it becomes a part of the circuit path so that all the current flowing through the load also passes through the ammeter, allowing for an accurate measurement of the current.
What is an ideal ammeter?
An ideal ammeter is a device that measures electric current and has zero resistance, producing no voltage drop when connected in a circuit. This ensures that the current being measured is not affected by the presence of the ammeter itself, providing an accurate reading of the current flowing through the circuit.
What is the difference between a galvanometer and an ammeter?
A galvanometer is a device used to detect small electric currents, while an ammeter is a device used to measure the strength of electric currents. The main difference is that a galvanometer is more sensitive and used for detecting small currents, while an ammeter is used for measuring larger currents.
Moving coil galvanometer converted into a multi range ammeter?
To convert a moving coil galvanometer into a multi-range ammeter, you can add shunt resistors of different values in parallel to the galvanometer. By selecting the appropriate shunt resistor, you can change the range of the ammeter. This allows the ammeter to measure a wide range of currents while still using the sensitive galvanometer as the measuring element.

Yes

How can you convert galvanometer into ammeter?
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. In this way a Galvanometer is converted into Ammeter and can measure heavy currents without fully deflected.
What is a VA burden of ammeter?
The VA burden of an ammeter refers to the amount of power that the ammeter itself consumes or requires to operate while measuring current. This is expressed in volt-amperes (VA) and is a product of the voltage across the ammeter's internal resistance and the current flowing through it. A higher burden can affect the accuracy of current measurements, especially in low-current applications, as it introduces additional resistance and can alter the circuit conditions. Therefore, selecting an ammeter with an appropriate burden is crucial for accurate measurements.
