Questions
A potentiometer is used for the comparison of e.m.f. of two cells E1 and E2. For cell E1 the no deflection point is obtained at 20 cm and for E2 the no deflection point is obtained at 30 cm. The ratio of their e.m.f.'s will be
detailed solution
Correct option is A
Ratio will be equal to the ratio of no deflection lengths. Hence, E1E2 = l1 l1 = 23Talk to our academic expert!
