Question
An inductor also has a reactance. The inductive reactance XL can be modeled as
XL=L
Where L is the inductance of the inductor. For a purely inductice circuit Z=XL
a. If the angular frequence of the circuit is large, is the circuit changing rapidly or slowly?
b. Given an inductor of fixed inductance L, in a circuit with very large angular frequency, is XL Large or small?
c. Given an inductor of fixed incuctance L, in a circuit with a very large angular frequency, does the current flow quickly or slowly in the circuit?
d. If you had a circuit with both a capacitor and inductor in it, how would you expect the curren to behave at low angular frequencies? At high angular frequencies?
Explanation / Answer
a) slowly.
b) large
c) slowly
d) at low frequency Xc is lage and at higher frequency XL is large so in both cases current is small
