... The charge varies with time as q 5 Qfinal 1 1 2 e 2t/RC 2 (Equation 19.17). In a time t 5 RC, there is a significant change in the charge on the capacitor. This time is called the time constant, or relaxation time, and is the same for charging or discharging. *Applications of Currents (Sections 19.9 ...

Electromigration
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.
