Conversion of Galvanometer to Voltmeter Quiz

What is the primary goal of the experiment described in the video?

• To measure the resistance of a galvanometer

• To convert a galvanometer into a voltmeter

• To determine the voltage range of a battery

• To calculate the current through a circuit

Which of the following is NOT listed as a required material for the experiment?

• A thermometer

• A battery eliminator

• A galvanometer

• A rheostat

How is the current required for full-scale deflection in the galvanometer calculated?

• By multiplying the number of divisions by the figure of merit

• By subtracting the figure of merit from the resistance

• By dividing the voltage by resistance

• By adding the resistance and voltage

What is the purpose of connecting a high resistance box in series with the galvanometer?

• To increase the current flow

• To convert the galvanometer into a voltmeter

• To measure the resistance of the circuit

• To decrease the voltage range

What is the least count of the converted voltmeter in this experiment?

• 1 volt per division

• 10 volts per division

• 0.01 volt per division

• 0.1 volt per division

During the verification process, why is sandpaper used on the connecting wires?

• To change the wire's color

• To increase the wire's length

• To decrease the wire's resistance

• To remove the insulating layer

In the verification setup, how are the voltmeter and converted galvanometer connected?

• In parallel with the rheostat

• In series with the battery

• In parallel with each other

• In series with each other

What role does the rheostat play in the verification process?

• It increases the resistance

• It acts as a current source

• It measures the voltage

• It functions as a potential divider

How is the error between the voltmeter and galvanometer readings calculated?

• By multiplying the two readings

• By subtracting the galvanometer reading from the voltmeter reading

• By dividing the voltmeter reading by the galvanometer reading

• By adding the two readings

What conclusion is drawn from the experiment regarding the conversion?

• The conversion is verified with minimal error

• The conversion is unsuccessful due to high error

• The conversion is not possible with the given materials

• The conversion results in a new voltage range
