Alternating CurrentHard
Question
When 100 V DC is applied across a solenoid, a steady current of 1 A flows in it. When 100 V AC is applied across the same solenoid, the current drops to 0.5 A. If the frequency of the AC source is 150 √3/π Hz, the impedance and inductance of the solenoid are :
Options
A.200 Ω and 1/3 H
B.100 Ω and 1/16 H
C.200 Ω and 1.0 H
D.1100 Ω and 3/117 H
= 100Ω x = 
= 200 Ω L =
