P. 303
Average power in a purely inductive circuit,
P = 0 (3.10)
Hence, the average power absorbed by a pure inductor is zero.
We had earlier taken,
The opposition to current is ωL. This is called inductive reactance, X L
which is X = ωL = 2πfL Ω.
L
The opposition offered by an inductor to the flow of current is X which is
L
equal to ωL This is called the inductive reactance and is expressed in Ohms.
Inductance, L is expressed in Henry.
As mentioned earlier, the values of alternating quantities are expressed in
terms of their effective or RMS values rather than their maximum values.
Therefore,
