A typical diode has a band on one end of the diode. That is considered the positive end. Current is considered to flow from the negative end to the positive end. In power diodes, they can be of two types-- positive polarity and negative polarity. Power diodes are usually designed with one end of the diode to be mounted in a heat sink. Since the desire is to allow current to flow in only one direction, the engineering of the circuit determines which way the current is designed to flow, hence the designation of positive or negative diodes especially for power diodes. A typical car alternator has 3 positive diodes and 3 negative diodes for a total of six.
A light emitting diode does not conduct in both directions.
A: The principle is that is a semiconductor meaning will conduct one way only. A switching diode however will have the least of capacitance across its junction so when it disconnect is faster
A diode will only conduct electricity if the polarity of the current is in the correct direction, because diodes can only conduct in one direction.
A: must assume an AC source of greater amplitude of .7volts then when the source reaches .7 volts a diode will conduct if the positive voltage is at the anode then it will proceed to go trough the load and return the current to the diode connected to the negative of the source. That basically finishes one half of the cycle when the AC reverses polarity then the same process of current flow will finish the complete cycle. while different series diode conduct one way the other will not conduct because of reverse biasing. but the load will conduct current one way for both cycles
forward bias
In one way it will, in the other it won't
A light emitting diode does not conduct in both directions.
Forward biased is the configuratiuon that a diode conducts.
a diode will conduct when anode is more positive than the cathode

forward bias
A diode is a silicon semiconductor meaning it will conduct one way because of the pphysical doping during manufacture
A: A diode array that will conduct if anyone of them are hi as in gates
place the multimeter on the diode. then connect the plobs to the hv diode. it can only conduct in one direction, not both ways. good luck
A diode is a semiconductor meaning it will conduct from anode to cathode if the anode is held positive. Reversing the polarity Will in effect block current flow.
