In experiments using the metre bridge, post office box and potentiometer, a galvanometer is used. Which property of the galvanometer makes it suitable for these experiments?
A
It has a relatively high coil resistance
B
It indicates rather than measures the magnitude of the current
C
It can indicate currents flowing through it in either direction
D
It can be made very sensitive to small currents
Answer
It can indicate currents flowing through it in either direction
Explanation
Solution
In the three experiments, the jockey is moved according to the direction of the deflection of the galvanometer.
