Teaching RPSC School Lecturer Mock Test Series 2024 Physics Moving Charges and Magnetism The Moving Coil Galvanometer
A teacher in his physics laboratory allotted an experiment to determine the resistance (G) of a galvanometer. Students took the observations for \(\frac{1}{3}\) deflection in the galvanometer. Which of the below is true for measuring value of G?
1
\(\frac{1}{3}\) deflection method cannot be used for determining the resistance of the galvanometer.
2
\(\frac{1}{3}\) deflection method can be used and in this case the G equals to twice the value of shunt resistance(s)
3
\(\frac{1}{3}\) deflection method can be used and in this case, the G equals to three times the value of shunt resistance(s)
4
\(\frac{1}{3}\) deflection method can be used and in this case the G value equals to the shunt resistance(s)
