Two 10 H inductors are in parallel and the parallel combination is in series with a third 10 H inductor. What is the approximate total reactance when a voltage with a frequency of 7 kHz is applied across the circuit terminals?
219 k
66 k
660 k
1.3 M

Total inductance=1/(1/10+1/10) +5 =15 H.

Now, total inductive reactance = 2*3.14*f*L = 2*3.14*15*7000 = 660000 ohm (APPROX).

XL = 2 *3.143*7*15.
= 660kohm.

XL = 2ΠfL = 2*3.14*7000*15 = 659400= That means Approximately 660k ohm.
