35. Two Cells in series give a deflection of when connected to a tangent galvanometer and the cells aid each other. The deflection reduce to when the cells oppse each other. The ratio of emf's of the cells in order is:
a. 1: 2
b. 2:1
c. 3:1
d. 1: 3
Dear Student ,
As we know that in case of tangent galvanometer we can write that ,
So the correct option is c .
