Question

Two inductor coils with inductance 10mH and 20mH are connected in parallel. What is the resultant inductance of the combination of the two coils ………….


(a) 20mH (b) 30mH
(c ) 10mH (d) 20/3mH​

Answer 1

Explanation:

1/L(parallel)= 1/(L)1 + 1/(L)2

1/L(parallel) = 1/10 +1/20

1/L(parallel)= 3/20

therefore, L(parallel)= 20/3 mH
