A galvanometer is a type of ammeter an instrument for detecting and measuring electric current.
A galvanometer can be converted into ammeter by connecting resistance in parallel with it.

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.
What value of resistance is used to convert galvanometer into voltmeter?
It depends on the resistance of the galvanometer and its full scale current. A 100 ohm meter reading 1 milliampere would require 0.1 volts to reach full scale, so it would require about 0.1 ohms in parallel to become a 1 ampere ammeter.
Why do you connect galvanometer in series?
You connect a galvanometer in series with the circuit being measured, because the galvanometer is a form of ammeter, although an extremely sensitive one, and ammeters measure the current in a series circuit.
What is the difference between a galvanometer and an electric motor?
Well, both work on what is termed the 'motor principle', i.e. a current-carrying conductor, when placed in a magnetic field, is subject to a force perpendicular to that field. But that's where the similarity ends, for the operating coil in a galvanometer is restricted to move within an arc, whereas a motor's coil will continuously rotate.
Can multimeter be used as voltmeter and ammeter?
Put a known small resistance (maybe 1 ohm) in parallel to it. Then use the equation I=V/R (R being the known resistance, and V being the voltage readout) So when using a 1 ohm resistor, if the voltmeter reads 2.35V, it means I=2.35/1 = 2.35 A
How you convert galvanometer into ammeter in detail?
By attaching a resistance in parallel connection with the galvanometer. Or when a low resistor connected in parallel with galvanometer ,the galvanometer is converted in ammeter. and the resistor is called shunt resistance.
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.
How do you convert a galvanometer to an ammeter?
A galvanometer is an instrument used to measure and detect electric currents. While that seems a lot similar to an ammeter, it only deals with measuring relatively small or mediocre currents. Although an ammeter is now much preferred due to its more accurate, faster, and advanced readings, there is a way to "convert" a galvanometer to function like an ammeter. A current separator or divider, known as a shunt, allows a simple meter to be calibrated (adjusted) to measure larger currents. The shunt, parallel to the coil of your galvanometer, allows more electric currents to circulate around the circuit, thus obtaining more current.
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 do you convert galvanometer to ohmmeter?
Ohms are the unit of measurement for resistance, so an ohmmeter is a device that measures electrical resistance. A galvanometer measures the current flowing through the resistance, so the two are related. To convert a galvanometer into an ohmmeter, one needs an external battery.
How do you convert galvanometer to an ohmmeter?
"An ohmmeter is an electrical instrument that measures electrical resistance, the opposition to an electric current."The unit of measurement for resistance is ohms (Ω).It is useful device for rapid measurement of resistance. It is consist of galvanometer and adjustable resistance Rs of known value and a cell connected in series. The resistance R to be measured is connected between the terminals.The series resistance Rs is so adjusted that when the terminals are short circuited i.e., when R = 0, the galvanometer gives full scale deflection. So the extreme graduation of the usual scale the galvanometer is marked 0 for resistance measurement. When terminals are not joined no current passes through the galvanometer and its deflection will be zero . Thus zero of the scale marked as infinity. . When R is not infinite , the galvanometer deflects to some intermediate point depending on the value of R scale can be calibrated to read the resistance directly.
What is the difference between ammeters and amp meters?
An Ammeter connects a low impedance on the test points, so the equivalent of that is a "short circuit" between the test points. This is done to avoid a drop of current on the tested circuit. A Voltmeter connects a high impedance on the test points, so the equivalent of that is a "open circuit" between the test points. This is done to avoid a drop of voltage on the tested circuit. --------- In terms of external connections Ammeter (used to measure current) is connected in series of the circuit (through which the current flow need to be measured) and voltmeter (used to measure voltage) is connected in parallel to points in circuit (across which voltage needs to be measured).
What value of resistance is used to convert galvanometer into voltmeter?
It depends on the resistance of the galvanometer and its full scale current. A 100 ohm meter reading 1 milliampere would require 0.1 volts to reach full scale, so it would require about 0.1 ohms in parallel to become a 1 ampere ammeter.
What is ammeter used for?
An ammeter measures the electrical current in something. A digital one is calibrated to display through the shunt and convert information from the analog model.

How do i convert mulitmeter readings?
For example: If its set to 2000uA, does that mean 2000uA per A?
What resistance value is add to convert a galvanometer into a voltmeter?
It depends on the resistance of the galvanometer and the current required to reach full scale. A 100 ohm meter requiring 1 milliampere would require 99.9 KOhms in series to become a 100 volt voltmeter.
