Q Define: self inductance.
The coefficient of self induction of a coil is numerically equivalent to the opposing emf induced in the coil when the rate of change of current through the coil is unity. The unit of a self inductance is henry (H).
Briefly explain resonance? Write down the condition of resonance for weak damping?
A coil of area 100 cm 2 having 500 turns carries a current of 1mA. It is suspended in a uniform magnetic field of induction 10 -3 Wbm -2 . Its plane makes an angle of 600 with t
Explain the Conservation of Momentum In a collision, energy is not all time conserved, if not the collision is totally elastic (all stored energy is turned into kinetic energy
Because force=dp/dt and force=0 in first law of motion => dp/dt=0 => p=const. or linear momentum is conserved.
