You're connecting a resistance in parallel with the ammeter, so that when the meter
and the additional resistor are inserted into a current-carrying circuit, a part of the
current goes through the meter, and the rest of the current bypasses the meter
and goes through the resistor instead. If you know exactly how much the split is,
then you can calculate the larger total current from the smaller number that you
read on the meter, so the meter is now able to measure and display more current
than it could before ... the range of its measurement ability has been extended.
Example:
-- You know the resistance of the meter.
-- You connect a resistor with exactly that same resistance in parallel with the meter.
-- Now 1/2 of the current goes through the meter and 1/2 goes through the resistor.
-- The total current is exactly double what you read on the meter.

How range of a ammeter is extended?
if we take resistance in parallel with ammeter then the range of ammeter will change.
To increase the range of a dc ammeter you would use a?
To increase the range of an ammeter, you connect a very low impedance resistor in parallel with the ammeter.
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.
How would you connect an ammeter if you want to measure the current coming through some device in a circuit?
HOW TO CONNECT AN AMMETER Always connect an ammeter in SERIES in a circuit. Always ensure that the ammeter has a higher reading range than the expected current load, including start-up spikes. An ammeter expected to read a steady current of 13A should have a max range of 20A.
What is a multi range voltmeter?
Multi-range ammeter using universal shunt
How shunt helps to extend the range of ammeter?
A shunt is connected in parallel with an ammeter. Any current applied to parallel devices will divide betwen them, so the ammeter will pass only a part of the total current.
How do you connect an ammeter and voltmeter?
To connect an ammeter, you must place it in series with the circuit so that the current flows through the ammeter. To connect a voltmeter, you must place it in parallel with the component you are measuring the voltage across. Make sure to set the ammeter and voltmeter to the proper range before connecting them.
How do you calculate the ammeter reading?
The voltage remains the same across the circuit as it is a parallel connection. So, the current across the upper half of the circuit where the ammeter is connected is calculated as I = V/R = 12.04 (total voltage)/12 (Resistance R1) = 1 A. Hence, the ammeter will read 1 A.
Aryton shunt multirange DC Ammeter?
aryton shunt in a multirange ammeter is basically a bunch of resistors(shunt) connected together in parallel to the Dc ammeter and a selector switch in order to basically extend the range of the current...
What is the scale division of ammeter?
The scale division of an ammeter refers to the value each division represents on the scale of the meter. It is typically chosen based on the range and precision of the measurement required. For example, if an ammeter has a scale division of 0.1 A, each division on the scale represents 0.1 ampere.
How would you extend the range of a voltmeter and ammeter?
if we would like to expand the range of voltmeter we should change the voltmeter resistance even to be appropriate . we should use a variable resistance to control of its value . I would extend the range of a voltmeter by adding resistance in series with it. I would extend the range of an ammeter by connecting resistance in paerallel with it.
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.
