Physics · Current Electricity
A teacher in a physics laboratory assigned an experiment to determine the resistance (G) of a galvanometer using the half-deflection method. If the students recorded observations for a 13 deflection in the galvanometer, which of the following statements is true for measuring the value of G?
- 1The 13 deflection method cannot be used for determining the resistance of the galvanometer.
- 2The 13 deflection method can be used, and in this case, G equals twice the value of the shunt resistance (S).✓
- 3The 13 deflection method can be used, and in this case, G equals three times the value of the shunt resistance (S).
- 4The 13 deflection method can be used, and in this case, G equals the value of the shunt resistance (S).
Correct answer
The 13 deflection method can be used, and in this case, G equals twice the value of the shunt resistance (S).
