A circuit contains two inductors of 6.0-mH inductance in series placed in parallel with an inductor of 8.0-mH inductance. After one of the 6.0-mH inductors burns out, the repair person wants to replace all three inductors with one inductor of equivalent inductance. Assuming inductors combine in series and parallel the same way resistors do, what inductance should she use?
A. 3.0 mH
B. 3.4 mH
C. 4.8 mH
D. 11 mH
E. 20 mH
