What is the role of high resistance are connected in series with the galvanometer?

In order to convert a galvanometer into voltmeter, a high resistance is connected in series with the galvanometer coil.

What happens if galvanometer is connected in series?

The galvanometer is converted into the ammeter by connecting the resistance in parallel with the circuit. And if the resistance is connected in series with a galvanometer, then it is used as a voltmeter. It is connected in series with the circuit for determining the exact value of circuit current.

What is the function of high resistance R connected in series with the galvanometer does this high resistance R affect the balance point?

the high resistance with the galvanometer is just to limit the current through the galvanometer when the voltage across the galvanometer is high because the internal resistance of the galvanometer is very low for high PD it can burn . so we put high resistance to keep it safe . it doesn’t effect the balance point .

What resistance should be connected in series of a galvanometer?

When a resistance of 100Ω is connected in series with a galvanometer of resistance R, its range is V. To double its range, a resistance of 1000 Ω is connected in series.

What is a high resistance galvanometer?

To make the resistance as high as possible a series resistance is connected to the Galvanometer to convert it to a voltmeter. It also serves the purpose of protecting the Galvanometer from damage due to high current.

What is resistance of galvanometer?

the galvanometer resistance equals that value of the variable resistance in the two methods. which gives the same second deflection. A new method which resembles the Kelvin method of. obtaining the resistance of a galvanometer is reported.

What is the role of high resistance in the circuit?

Resistance measurements are normally taken to indicate the condition of a component or a circuit. The higher the resistance, the lower the current flow. If abnormally high, one possible cause (among many) could be damaged conductors due to burning or corrosion.

What is the purpose of using high resistance?

High resistance is used in potentiometer since while measuring the EMF of a cell, it does not draw any current from the source of known EMF.

Why is a high resistance resistor connected in series with the potential coil?

Higher resistance give more accurate voltage reading, So, we connect many resistor in series so that resultant resistance across line should be high and no(very less) current should pass through it and all current should force to pass through current coil, this will lead accurate reading of current .
