A semiconductor diode is a non-linear device whose most outstanding feature is the fact that, basically, current is only allowed to flow in one direction. The diode is built by joining together two ...

General purpose diodes are two-terminal electronic components that allow current to flow in only one direction, from an anode (+) to a cathode. These simple semiconductors are PN junctions with a ...

The diode has a very high resistance in one direction. This means that current can only flow in the other direction. This is the graph of current against voltage for a diode. Normally a diode will ...

The concept of rectification—where current flows more easily in one direction than the other—is essential for the functioning of many electronic devices, from diodes to transistors.
