The Total solution for NCERT class 6-12
Three capacitors of capacitances 2 pF, 3 pF and 4 pF areconnected in parallel.
(a)┬аWhat is the total capacitance of the combination?
(b)┬аDetermine the charge on each capacitor if thecombination is connected to a 100 V supply.
(a)┬аCapacitances of the given capacitors are
Therefore, total capacitance of the combination is 9 pF.
(b)┬аSupply voltage,┬аV┬а= 100 V
The voltage through all the threecapacitors is same =┬аV┬а= 100 V
Charge on a capacitor of capacitance┬аC┬аandpotential difference┬аV┬аis given by the relation,
q┬а=┬аVC┬атАж(i)
For C = 3 pF,
For C = 4 pF,
