Solving Electric Potential: Find Charge on Parallel-Plate Capacitor

In summary, a parallel-plate capacitor is a device that stores electrical energy by creating an electric field between two parallel plates. The electric potential of a parallel-plate capacitor can be calculated by dividing the charge on one plate by the capacitance of the capacitor. The relationship between charge and electric potential in a parallel-plate capacitor is directly proportional. The charge on a parallel-plate capacitor can be found by multiplying the capacitance by the electric potential. The factors that affect the charge on a parallel-plate capacitor include the capacitance, distance between the plates, voltage applied, and properties of the dielectric material.

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!)
 

What is a parallel-plate capacitor?

A parallel-plate capacitor is a device that stores electrical energy by creating an electric field between two parallel plates. It consists of two conductive plates separated by a dielectric material, such as air or glass.

How do you calculate the electric potential of a parallel-plate capacitor?

The electric potential of a parallel-plate capacitor can be calculated by dividing the charge on one plate by the capacitance of the capacitor. The equation is V = Q/C, where V is the electric potential, Q is the charge, and C is the capacitance.

What is the relationship between charge and electric potential in a parallel-plate capacitor?

The relationship between charge and electric potential in a parallel-plate capacitor is directly proportional. This means that as the charge on the plates increases, the electric potential also increases, and vice versa.

How do you find the charge on a parallel-plate capacitor?

The charge on a parallel-plate capacitor can be found by multiplying the capacitance of the capacitor by the electric potential. The equation is Q = CV, where Q is the charge, C is the capacitance, and V is the electric potential.

What factors affect the charge on a parallel-plate capacitor?

The charge on a parallel-plate capacitor is affected by the capacitance, the distance between the plates, and the voltage applied to the capacitor. Additionally, the type and properties of the dielectric material between the plates can also affect the charge.
