Dear student

A reduction factor of a tangent galvanometer is equal tocurrent, required to be passed through the galvanometer to produce a deflection of 45∘. The reduction factor is measured in ampere

Dear student 
i∝tanφ⇒i1/i2=tanφ1/tanφ2
⇒0.1/i2=tan30∘/tan60∘=1/3⇒i2=0.3A
Good Luck …...............................................................
