Question

How does inserting an iron rod into the inductor affect its inductive reactance?

विकल्प

• The inductive reactance of the coil decreases.

• The inductive reactance of the coil increases.

• The inductive reactance of the coil becomes zero.

• The inductive reactance of the coil is unchanged.

Answer 1

Inserting the iron rod increases the inductance of the coil. Consequently, the inductive reactance of the coil increases.
