Alternating CurrentHard
Question
In the given a.c. circuit, choose the correct statement(s).In the given a.c. circuit, choose the correct statement(s).
Options
A.Impedance of circuit is 2Ω
B.Power factor of circuit is 
C.Peak value of current through resistance is 50√2 A
D.Average power supplied by source is 2500 W.
Solution
i20 =
= 50 √2 A⇒ i10 = 50 A
Phase difference between v and i is θ = 0o
i = i1 + i2
i0 = 50.
Pav =
cos θ = 2500Wz =
= 2Ω
