In the following circuit, what is the total charge on the combination of capacitors?

Question

Professor PC Thomas Classes · Answer

Equivalent capacitance $C_{eq} = (\frac{1}{6} + \frac{1}{5+7})^{-1} = 4\mu	ext{F}$. Charge $Q = C_{eq}V = 4\mu	ext{F} 	imes 50	ext{V} = 200\mu	ext{C} = 2 	imes 10^{-4}	ext{ C}$.
