The resistances of the four arms of a Wheatstone bridge are as follows: AB = 100, BC = 10, CD = 4, DA = 50 ohms. A 20-ohm resistance galvanometer is connected between BD. If there is a potential difference of 10 V across the AC, then find the value of the current flowing through the galvanometer.
Consider the following in context of creeping in energy meter and identify the correct option.
P: The primary reason of creeping is under-compensation for friction.
Q: Creeping may be because of excessive voltage and vibrations.
