a parallel-plate capacitor is formed from two 4.0 cm x 4.0 cm electrodes spaced 2.0 mm apart. the electric field strength inside the capacitor is 1.0 x 106 n/c. what is the charge (in nc) on each electrode?



Answer :

Equation Q/A = E Electric Field within a parallel plate capacitor

Q = E*Aε

E = 10^6 N/C

A = 4*4 = 16cm^2 = 16 * 10^-4 m^2

ε = 8.852 * 10^-12 F/m

Q = +/- 10^6 * 16 * 10^-4 * 8.852 * 10^-12

= +/- 141.6 * 10^-10 C

= +/- 14.2 nC

You can think of an electric field as a physical field that surrounds all charged particles and pulls on them all.

Before the dielectric breaks down, a parallel plate capacitor can only hold a certain amount of energy. It can be stated as follows: The parallel plate capacitor is a device that uses two parallel plates connected across a battery to create an electric field between them.

A nonmetallic component of a circuit is made in touch with using an electrode, an electrical conductor. Depending on the type of battery, electrodes are a crucial component that can be made of a range of materials.
