... Copper and aluminum are being considered for a high-voltage transmission line that must carry a current of 60.0 A. The resistance per unit length is to be 0.150 Ω/km.The densities of copper and aluminum are 8960 and 2600 kg/m 3, respectively. Compute (a) the magnitude J of the current density and (b ...

... In our discussion so far we have considered field problems that are associated with static charges. In this chapter we consider the situation when the charges can be in motion and thereby constituting current flow. Due to the movement of free charges, several types of electric current can be caused: ...

Current and Continuity Equation
... In our earlier discussion we have mentioned that, conductors have free electrons that move randomly under thermal agitation. In the absence of an external electric field, the average thermal velocity on a microscopic scale is zero and so is the net current in the conductor. Under the influence of an ...

Electromigration
![](https://commons.wikimedia.org/wiki/Special:FilePath/Electromigration.png?width=300)
Electromigration is the transport of material caused by the gradual movement of the ions in a conductor due to the momentum transfer between conducting electrons and diffusing metal atoms. The effect is important in applications where high direct current densities are used, such as in microelectronics and related structures. As the structure size in electronics such as integrated circuits (ICs) decreases, the practical significance of this effect increases.
