When a shunt resistor is connected in series with an ammeter, it allows the ammeter to measure larger currents than it can handle directly. The shunt resistor creates a parallel path for most of the current to flow through, allowing only a small fraction of the total current to pass through the ammeter itself. This setup enables the ammeter to accurately measure the current by using the voltage drop across the shunt resistor, which can be calibrated to reflect the total current flowing in the circuit.
What else can I help you with?
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.
Why shouldn't ammeter be connected in parallel?
A: An ammeter actually is a voltmeter measuring the voltage drop across a very small shunt resistance. They can measure AC or DC, make sure the meter is rated for the anticipated current, and always connect in series.
How do you connect resistor?
In a circuit, either in Parallel or in Series with other components.
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 happen if you change the position of ammeter in the circuit in parallel and series?
-- In a series circuit, no matter where you install the ammeter, it will always read the same current. -- In a parallel circuit, the ammeter may read a different current when it's moved to a different parallel branch.
How do you find amperes when using a resistor?
if you want to find the current (in amperes) through the resistor then connect a ammeter in series with the resistor.
How do you connect a ammeter into a circuit?
connect ammeter in series with load.
High resistance in parallel connected with galvanometer to form voltmeter?

What effect if any does connecting an ammeter in series with a resistor in a circuit have on the current though the resistor?
Connecting an ammeter in series with a resistor in a circuit will not affect the current through the resistor. The ammeter measures the current passing through it, so it becomes part of the circuit and simply measures the current flowing through the resistor without changing it.
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.
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 is an ammeter connected in a circuit?
Series connect it within the line of the circuit for which you are interested in measuring the current flow.More detailSince we measure the flow of current IN the circuit, the ammeter must be connected in series with the part of the circuit for which you are interested in measuring the current flow.One of the ammeter's terminals must be connected to a point of the incoming current flow and its second terminal must be connected to the point of on-going current flow. To do this, cut the relevant circuit wire and connect one terminal of the ammeter to each end of the cut.
Why shouldn't ammeter be connected in parallel?
A: An ammeter actually is a voltmeter measuring the voltage drop across a very small shunt resistance. They can measure AC or DC, make sure the meter is rated for the anticipated current, and always connect in series.
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.
How do you connect resistor?
In a circuit, either in Parallel or in Series with other components.
How do you connect resistance is series?
I'm going to take this as "How do you connect resistors is series?" just connect one wire of the first resistor to one wire of the second.
How is an ammeter converted to a voltmeter?
