Case : Read the passage and answer the question(s). Number of magnetic field lines crossing a surface is called the magnetic flux. An electric current can be induced in a coil by flux change produced by another coil in its vicinity or flux change produced by the same coil. The former is called the mutual induction and the latter is called the self-induction. An induction furnace works on this principle. |
A material is taken and made into two coils. Coil A is wound in square turns while Coil B is wound in circular turns. Then which of the following is true? |
The resistance of coil A is greater The resistance of coil B is greater The inductance is same The inductance is different |
The inductance is different |
Inductance depends on the geometry of the coil. |
