I remember which end is the anode because the arrowhead in the symbol for a diode looks like an "A" (for Anode) on its side. It points in the direction of "conventional" positive-to-negative (P-to-N) current flow, which reminds me that the anode has P-type semiconductor, and the cathode has N-type semiconductor. The vertical line for the cathode represents a wall that blocks "conventional" current from going from cathode to anode. That "wall" is represented by a ring marked around the cathode end of a "physical" diode.

Electrons flow from negative to positive?

@farjanasharminswarna2450 5 жыл бұрын

Yes. Electrons flow from negatively charged area to positively charged area. Therefore, current which is a flow of electron vacancy or hole, flows from positive to negative. If you add a battery to a circuit then current will flow from the positive terminal of the battery towards the negative terminal of the battery through all the other elements in the circuit. To ease the confusion, think of heat flow according to thermodynamics. Heat flows from high temperature area to low temperature area. Also if you think of water, it flows towards the area where water is less or the pressure is less. Just like that everything in nature flows from it's majority towards it's minority. In a negatively charged area, electrons are higher in number. So electron flows from negative to positive. Current flows in the opposite direction of electron flow. So, current flows from positive to negative.

@JonAhlquist Жыл бұрын

Researchers who study the psychology of learning have found that the order in which you learn something is not important. That is good because we rarely have the time or opportunity to start something "from the beginning," which is different for different people because of their different backgrounds. It is fine to "fill in" your understanding as needed. I can't say much more because KZfaq does not allow posts that provide or even suggest links elsewhere.

Does diode block the flow of electrons as it does to current in flowing in one direction, since electrons flow in opposition with current. I.e diode allow current flow in one direction, block it in opposite direction, while electrons flow in opposite direction, will the electron b blocked hence it's flowing in the direction diode is blocking.

I dont unerstand why the naming is different compared to a battery. I thought the anode of a battery was the negatively charged terminal that has excess electrons, so why would the anode of a diode be the electron deficient part that contains holes, its just confusing. I was just reading somehting and had a thought: Is the anode of a battery actually initially positively charged, becoming negatively charged only when the chemical reaction happens within the battery and the resulting free electrons are attracted towards it?

Hey, I think you made a mistake. Electric components in the electric circuits never consume power unless they have internal resistance. Since you provided that the diode has a voltage of .7 volts, this means it is ideal one so it has no resistance and, thus, consumes no power

@JordanEdmundsEECS 6 жыл бұрын

Any electrical component with a positive voltage across it and a positive current flowing into the positive terminal consumes power. The idea of "resistance" is only a linear approximation to much more complex phenomena, such as what happens in a diode. The only power equation that always applies is P =V*I

@felixcat4346 5 жыл бұрын

If there is a voltage drop of .7 volts across the diode it must be consuming current when it's in the forward bias mode. Its simple ohm's law.

It is on because the source voltage is in negative value, flowing through the cathode (negative terminal) side of the diode. If the negative voltage source is flowing through the anode (positive terminal) then the current wont flow.

@BenjaminK2 7 ай бұрын

At @6:20 he assumes the voltage across the diode is exactly 0.7V, but there is no reason to assume this! Surely, the diode can have a range of possible voltage values across it, as seen in the diode's Voltage, Current graph @3:30. This variable diode Voltage presumably increases as a result of increasing the source Voltage. In light of this point, how does one then properly calculate the resulting voltages, and current?
