A)14.3 mH
B)70 mH
C)50 mH
D)20 mH

Question

Quizplus · Accepted Answer

The total inductance of inductors connected in parallel is found using the formula 1/L_total = 1/L1 + 1/L2 for two inductors. For a 20 mH and a 50 mH inductor in parallel, 1/L_total = 1/20 + 1/50 = 5/100 + 2/100 = 7/100. Therefore, L_total = 100/7 = 14.2857 mH, which rounds to 14.3 mH.
