Question
Alternating current is flowing in inductance L and resistance R. The frequency of source is 
. Which of the following statement is correct : -
. Which of the following statement is correct : -Options
A.for low frequency the limiting value of impedance is L.
B.for high frequency the limiting value of impedance is Lω.
C.for high frequency the limiting value of impedance is R.
D.for low frequency the limiting value of impedance is Lω.
Solution
Impedance = 
At low frequency ω → 0
so impedance → R
At high frequency ω → ∞
so impedance → ωL
At low frequency ω → 0
so impedance → R
At high frequency ω → ∞
so impedance → ωL
