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.
A galvanometer can be converted into a voltmeter by placing?
a high resistance in series
What is a NULL Point of a galvanometer?
Its a point on the galvanometer where the galvanometer shows no deflection as no current passes through it.
Construction of ohm meter and megger?
Ohm meter is basically a series combination of resistances and galvanometer and source of current .Used to determine unknown resistance.
What are the readings for the experiment - to convert a galvanometer int ammeter?
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.
How can you connect a galvanometer to a curcuit?
To connect a galvanometer to a circuit, first, ensure the galvanometer is rated for the voltage and current levels of your circuit. Connect the positive terminal of the galvanometer to the positive side of the circuit and the negative terminal to the negative side. Optionally, include a resistor in series to limit the current and protect the galvanometer from damage. Finally, ensure all connections are secure to maintain accurate readings.
High resistance in parallel connected with galvanometer to form voltmeter?

What should you do to convert a galvano meter into volto meter?
Connect a large but precisely known resistance in series with the galvanometer. For example, if you connect a 1-Megohm resistor in series with it, then the galvanometer will indicate 1 microampere of current when it's connected across a potential difference of 1 volt ... quite a sensitve voltmeter.
How galvanometer measure the exact voltage with series high resistor?
Assuming galvanometer has zero or negligible internal resistance. If u connect resistor R>>RL(Load resistance) and connect it parallel to RL, it will hardly cause any change in voltage across load resistance. Suppose small current Ig goes through galvanometer. Since galvanometer have zero internal resistance, Voltage across RL = Voltage across R = IgR
What is the circuit diagram on how to convert galvanomeer into ohmeter?
Just connect a resistor and a small battery in series with the galvanometer,change the markings on the meter's scale, and you have an ohmmeter.
A galvanometer can be converted into a voltmeter by placing?
a high resistance in series
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.
How do you induce polarity in galvanometer?
To induce polarity in a galvanometer, you can connect the positive terminal of a power source to one terminal and the negative terminal to the other terminal. This creates a potential difference across the terminals of the galvanometer, inducing polarity in the device.
A moving coil galvanometer can be used as an ammeter by adding?
a series resistence with its coil
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 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.
