Webb10 mars 2014 · A diode is effectively like a valve for an electrical circuit. Semiconductor diodes are the most common type of diode. These diodes begin conducting electricity only if a certain threshold voltage is present in the forward direction (i.e. the “low resistance” direction). The diode is said to be “ forward biased ” when conducting current ...
