प्रश्न
Find the charge supplied by the battery in the arrangement shown in figure.
उत्तर
The equivalent circuit for the given case can be drawn as :-
It can be observed that capacitors C1 and C2 are in parallel.
Therefore, the equivalent capacitance is given by
Ceq = C1 + C2
= 5 + 6 = 11 μF
Now ,
Charge supplied by the battery = (Ceq)(V) = (11 μF) × (10 V) = 110 μC
