A long coaxial cable consists of an inner cylindrical conductor with radius a and an outer coaxial cylinder with inner radius b and outer radius c. The outer cylinder is mounted on insulating supports and has no net charge. The inner cylinder has a uniform positive charge per unit length lambda.

Calculate the magnitude of the electric field at any point between the cylinders a distance r from the axis.
Express your answer in terms of the variables a, b, c, r, lambda, and constants pi and epsilon_0.

Find the direction of the electric field at any point between the cylinders a distance r from the axis.

Calculate the magnitude of the electric field at any point outside the outer cylinder a distance r from the axis.
Express your answer in terms of the variables a, b, c, r, lambda, and constants pi and epsilon_0.

Find the direction of the electric field at any point outside the outer cylinder a distance r from the axis.

Find the charge per unit length on the inner surface and on the outer surface of the outer cylinder.

Neglect end effects. The region between the conductors is air. Ke =1/4*pi*epsilon= 8.98755e9 N m^2/C^2.
A coaxialcable has a charged inner conductor (with charge +4.8 microcoulombs and radius 1.199 mm) and a surrounding oppositely charged conductor (with charge -4.8 microcoulombs and radius 7.405 mm).

See attached file for clarity.
The electricfield outside a uniformly charged, infinite cylindrical conductor is the same as if the cylinder's charge were concentrated in a thin wire along the cylinders axis. Moreover, the potential inside a uniformly charged infinite cylindrical pipe like that inside a spherical shell is co

A coaxialcable consists of a wire of radius 'a' surrounded by a concentric conducting sleeve of inner radius 'b' and outer radius 'c'.
A current flows in the wire of radius 'a' out of the page; this current is spread uniformly over the cross section of the wire. An equal current flows in the opposite direction in the sleeve;

A. A long straight cable with radius R carries a current uniformly distributed through its circular cross section. Find the self-inductance per unit length of the cable. Hint: find B inside and outside, then find energy everywhere and relate to the self-inductance (per unit length)
B. This cable is now modified to have an ins

The electricfield is defined as the electrostatic force divided by the charge experiencing this force. The Earth's electricfield is directed radially inward and is about 150 N/C at the Earth's surface. This arises because in a region of the atmosphere known as the ionosphere, parts of the spectrum of the radiation from the sun

Point charges q1=- 5.00 nC and q2=+ 5.00 nC are separated by distance 3.80 mm, forming an electric dipole.

Hi. Can someone please explain to me what exactly the electric potential is and how it differs from electric potential energy -- not with equations, but in prose. (Or at least, with both.) I can read the equation, but I don't really understand what electric potential IS. What is its significance?
Thank you!
