Magnetic Field Of Coaxial Cable

The word coaxial means same axis. So for a long straight cable to be coaxial, it must have concentric cylindrical shaped conductor around it. Coaxial cable (popularly called ‘coax’) has various applications ranging from current conductors to radiofrequency signal transmitters. This cable has lower emission losses and provides protection from electromagnetic interference which allows signals with less power to transmit over longer distances.For example, currents produced in the pickup of a stereo turntable generally travel to the amplifier through a coaxial cable.The self-inductance of a coaxial cable is another important characteristic, because it influences the propagation of electrical signals in the cable.

(a) Calculate the acceleration of the electorn if the field strength is 2.50104 N/C. (b) Explain why the electron will not be pulled back to the positive plate once it moves through the hole.
When wool is rubbed against amber, the wool becomes positively charged and the amber becomes negatively charged. If you rub a glass rod with a silk cloth and an amber rod with a wool cloth, are the rods attracted to or repelled by each other? Are the cloths attracted to or repelled by each other? Is the silk cloth attracted to the amber rod or repelled by the amber rod? Is the wool cloth attracted to the glass rod or repelled by the glass rod? Explain your answers.

Compare and contrast the Coulomb force field and the electric field. To do this, make a list of five properties for the Coulomb force field analogous to the five properties listed for electric field lines. Compare each item in your list of Coulomb force field properties with those of the electric field—are they the same or different? (For example, electric field lines cannot cross. Is the same true for Coulomb field lines?)

(b) Discuss whether the magnitude of this charge is consistent with what is typical of static electricity.
