Final answer:
The charge stored on capacitor c1 is 144 microcoulombs (μC).
Step-by-step explanation:
To find the charge stored on capacitor c1, we need to use the equation Q = CV, where Q is the charge, C is the capacitance, and V is the voltage applied across the capacitor.
From the given information, we have a 12 μF capacitor with 12 V applied across it. Plugging in these values, we get:
Q = (12 μF) * (12 V) = 144 μC
Therefore, the charge stored on capacitor c1 is 144 microcoulombs (μC).
