I am unable to get the derivations of this chapter like the rms value , power of L,C and R etc . can you please help me out in any way ?

Average power consumed by inductor circuit:

The average power is

The average power is zero for reasons similar to the Capacitor case, in that there is no dissipative mechanism for the power to be lost into, since the states of the inductor and the EMF source are the same at the beginning and the end of any cycle. This happens here, because the energy is temporarily converted into magnetic energy stored in the magnetic field of the inductor. This is again obtained back in the second half of the cycle.
