A coil of inductance 300 mH and resistance `2Omega` is connected to a source of voltage 2V. The current reaches half of its steady state value
The self-inductance of a coil having 500 turns is `50 mH`. The magnetic flux through the cross-sectional area of the coil while current through it is 8 mA, is found to
Self-Induction Self-induction is the property of a coil by virtue of which the coil opposes any change in the strength of current flowing through it by inducing an emf in itself. This induced emf is also called back emf. When the current in a coil is switched ON, then the self induction opposes the growth of the current and when it is switch OFF, then the self-induction opposes the decay of the current.In 0.2s, the current in a coil increases from `1.5 A to 2.5 A`. If inductance of this coil is 60 mH, then induced current in an external
The self inductance of a coil is 5H, a current of 1A changes to 2A within 5 sec. through the coil. The value of induced emf will
