Questions
To form a composite capacitor from a supply of identical capacitors marked , we require a minimum number of capacitors
detailed solution
Correct option is B
Suppose C = 8 μF , C' = 16μF and V = 250 V, V' = 1000V Suppose m rows of given capacitors are connected in parallel and each row contains n capacitors then potential difference across each capacitor V=V'n and equivalent capacitance of network C'=mCn on putting the values we get n = 4 and m = 8∴Total capacitors = n × m = 4 ×8 = 32Talk to our academic expert!
