Many introductory books on electricity try to relate voltage to water pressure, electric current to water flow, and resistance to changes in pipe volume.

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.

Recommended Videos How does direct current work? Direct current is fairly straightforward. DC power strictly flows in one direction.

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.

It demonstrates how static electricity is created and how current electricity flows through complete circuits, using examples like a train and various experiments.
