Questions
The equivalent inductance of two inductances is 2.4 H when connected in parallel and 10 H when connected in series. The difference between the two inductances is
detailed solution
Correct option is A
Ls=L1+L2=10H …(i)Lp=L1L2L1+L2=2.4H …(ii)On solving (i) and (ii), L1L2=24 …(iii)Also L1-L22=L1+L22-4L1L2⇒L1-L22=(10)2-4×24=4⇒L1-L2=2HTalk to our academic expert!
