A solenoid with N loops of wire tightly wrapped around an iron-core is carrying an electric current I. If the current through this solenoid is reduced to half, then what change would you expect in inductance L of the solenoid. |

Answer» Given: I' = \(\frac{I}{2}\) Inductance, L = μo . \(\frac{N^2}{e}\).A l : length of solenoid N: number of lines A: area of cross- section of solenoid Since, 'I' is independent of current, so there is no change in the inductance of the solenoid. Remains same. |
