The key lies in that one-way valve we mentioned earlier. When the diode is forward biased and conducting electricity it will pass through any variations in the voltage being put into them ...

Diodes are used for a number of different applications, the most frequently being signal rectification, voltage clamping, reference-voltage circuits, light emitters, photodetectors, and solar cells.

Energy band diagram of pn junction under forward bias, Continuity equation, Boundary conditions, Ideal diode equation, Long- and short-base diodes, Recombination and generation in the depletion region ...

It also includes the symbol for a diode, showing the direction of conventional current flow when the diode is forward biased. (Image: Wikimedia Commons, CC SA 3.0) When a positive voltage is applied ...

Specific items of interest are: a) The capacitance versus voltage relation, b) The diode current, including minority carrier injection under forward bias, c) The minority carrier charge and its effect ...
