Question

What property of a coil is called self-inductance?

विकल्प

• The property by which it induces an emf only in a neighbouring coil

• The property by which it stores energy in an electric field

• The property by which it prevents magnetic flux through the coil

• The property by which it opposes the change in its own current and induces an emf in itself

Answer 1

Self-inductance describes a coil's response to a change in its own current. That change induces an emf in the same coil.
