Two tangent galvanometers a and b
WebEx. Two tangent galvanometers differ only in the matter of number of turns in the coil. On passing current through the two joined in series, the first shows a deflection of $35^{\circ}$ and the other shows a $45^{\circ}$ deflection. Calculate the ratio of their number of turns. Use tan $35^{\circ}=0.7$ Sol. WebJun 12, 2024 · Two tangent galvanometers A and B have coils of radii `8cm` and `16cm` respectively and resistance `8ohm` each. They are connected in parallel to a cell of emf `4V` and negligible internal resistance. The deflections produced are `30^@` and `60^@` respectivley. A has 2 turns. What is the number of turns in B?
