Two tangent galvanometers having coils of the same radius are connected in series. A current flowing in them produces a deflection of 60° and 45° respectively. The ratio of the number of turns in the coils is:
- \(\frac{4}{3}\)
- \(\frac{\sqrt{3+1}}{1}\)
- \(\frac{\sqrt{3}}{1}\)
- \(\frac{(\sqrt{3+1)} }{(\sqrt{3}-1)}\)
Answer
(C) 3 1
