Variation of pd v with l in case of two potentiometer x and y as shoqn

1.	Variation of pd v with l in case of two potentiometer x and y as shoqn in diagram
Answer» ong>Answer: ==>>> A potentiometer is CALLED sensitive if FALL of potential per unit length ie potential gradient is small. The slope of V-l graph GIVES a potential gradient which is SMALLER for the potentiometer wire Q than for potentiometer wire P. HENCE, potentiometer wire Q is more sensitive. Therefore, it will be more accurate and sensitive. Hence, the Potentiometer Q will be preferred than the Potentiometer P. Regards.
