Homework Help: Electric Potential

  1. Mar 2, 2008 #1
    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!)
