Verified answer
Given :
Inductance of inductor = 0.7H
Inductive reactance [tex]=[/tex] 220Ω
To Find :
We have to find frequency of alternating current[tex].[/tex]
Solution :
For an a.c. circuit containing inductor only, Inductive reactance is given by
X(L) denotes inductive reactance
ω denotes angular frequency
L denotes inductance
___________________________________
❅ Relation b/w angular freq. and freq. is given by, ω = 2πf
➝ X(L) = ωL
➝ X(L) = 2πf × L
➝ f = X(L) / 2πL
➝ f = 220/(2×3.14×0.7)
➝ f = 50Hz
