Solving Electric Potential: Find Charge on Parallel-Plate Capacitor

[spark2flame]

1. A parallel-plate capacitor filled with air has plates of area 0.0061 m2 and a separation of 0.65 mm. Find the magnitude of the charge on each plate when the capacitor is connected to a 12 V battery.



2. E = delta(V)/delta(s)



3. I keep getting the wrong answer by using the formula above, but I don't know how to solve for specific charges on plate capacitors!

How does charge relate to capacitance and voltage? How do you find the capacitance of a parallel plate capacitor? (Look it up!)
