$\huge\tt\longrightarrow\underline{\purple{♔︎A}\red{N}\blue{S}\green{W}\orange{E}\pink{R}}$

It is calculated as V/L, where V is the potential difference between two points and L is the distance between two points. Also K = (IρL/A)/L = Iρ/A. E1/E2 = L1/L2 is the equation to compare the emf of two cells, where E1 and E2 are the emf and L1 and L2 are the length at which it is balanced.
