To find the EMF of the cell in the potentiometer experiment, we will follow these steps: ### Step 1: Understand the relationship between resistance and length The resistance of the potentiometer wire is directly proportional to its length. Given that the total length of the potentiometer wire is 1 meter (100 cm) and its total resistance is 60 Ω, we can find the resistance per centimeter. ### Step 2: Calculate the resistance per centimeter The total resistance of the potentiometer wire is given as 60 Ω for 100 cm. Therefore, the resistance per centimeter (R_per_cm) can be calculated as follows: ...
