Two manganin wires whose lengths are in the ratio 1 : 2 and whose resistances are in the ratio 1 : 2 are connected in series with a battery. What will be the ratio of drift velocities of free electrons in the two wires?
since the ratio of length is same as that of resistance the area of crossection must be samesoi1=i2 (i=neAvd)so vd1=vd2 PLEASE APPROVE
