This means that current can only flow in the other direction. Normally a diode will not conduct until a particular voltage is reached. Ellie and James explore series and parallel circuits.

Resistance ® close resistance (R)How difficult it is for current to flow. increases when components, for example a lamp, are added to a circuit in series. Potential difference close potential ...

The N-channel/P-channel pair activated in each H-bridge sets current-flow direction ... demonstrates that as the series resistance rises, the current through the circuit drops.

switches direction 50 or 60 times per second, the current in DC circuits flows only in one direction. The electrons, which make up the electric charge, go from the point of low potential to the ...

the electrons are the charge carrier and flow from the battery’s negative terminal, around the circuit and back to the positive terminal. Conventional current takes just the opposite direction ...

In the very beginning, electrical pioneers really didn't know what direction current ... school and was taught that current flow was electron flow and all circuit analysis was done that way.

We talk about electrical current — just like current in a stream. Many introductory books on electricity try to relate voltage to water pressure, electric current to water flow, and resistance ...

including closed and open circuits, and the role of switches in controlling the flow of current. The video demonstrates experiments using dry cells to illustrate the principles of conductors ...
