Questions
You are given thirty two capacitors each having capacity 4 F. How do you connect all of them to prepare a composite capacity having capacitance 8 F?
detailed solution
Correct option is C
Let m condensers are joined in series and n such groups are in parallel.Capacity of m condensers connected in series1C′=1C1+1C2+…=mC or C′=Cm=4mWhen n such groups are connected in parallel, thenCeff=nC′=4nmGiven that Geff=8, ∴8=4nmOr nm=2 or n=2m ...(1)Further mn=32 ....(2)Now m×2m=32 or m=4and n = 2 x 4 = 8Talk to our academic expert!
