I came to engineering by way of the technician route. I learned electronics in a technical school and was taught that current flow was electron flow and all circuit analysis was done that way.

ORNL researchers are designing and increasing the capacity of a new type of semiconductor-based circuit breaker, which can ...

In contrast to alternating current, or AC, which, depending on the supply's frequency, switches direction 50 or 60 times per second, the current in DC circuits flows only in one direction.
