Question

Three inductors, each having inductance L, are connected in series and parallel combinations. The ratio of the inductance in series and parallel combinations is: 

1) 9:1

2) 1:9

3) 1:3

4) 3:1​

Answer 1

IN PARALLEL,

1/L(total)  = 1/L+ 1/L+ 1/L

L(total)=L/3

IN SERIES,

L(total)=L+L+L=3L

SO,

RATIO OF SERIES/PARALLEL IS,

=3L/L/3

=9L/L

=9:1

I HOPE MY ANS IS CLEAR!!THANK YOU!!
