Current snaps back to zero very rapidly
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.
There are two diode ratings. One is the forward current rating, and the other is the reverse breakdown voltage rating. The forward current rating is the maximum current that the diode can conduct before failing, and the reverse breakdown voltage rating is the maximum reverse voltage that can be applied before failing. Of course, the reverse voltage rating has a different meaning in a zener diode, but this answer applies to ordinary diodes.
if a diode is in forward biased the diode acts as switch is on and when we apply the diode in reverse biased then it work as the switch as off.
It depends on how the diode is damaged. There are generally two cases. One, the diode is shorted, and conducts with a low impedance in both directions. The other, the diode is open, and does not conduct, having a high impedance, in both directions. The effect depends on the particular circuit. In a power supply, a shorted diode will often blow the fuse, while an open diode will result in no output, or in high ripple voltage output. Is it possible that diode has normal voltage output but wrong current,meaning low mA?
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
No a diode will not work when the ignition key is off.

The difference in the 1N4007 diode and the 1N4007S diode is the voltage. The 1N4007S has a higher voltage but the meaning of the S is not listed.
A battery cannot be drained by a shorted diode when the ignition key is off.
light emitting diode and its a diode that emitting the light when the current passes through it and it used in the TV screen
Transistor will be in OFF mode.
Transistor will be in OFF mode.

I diode allows current to flow in only one direction. Therefore, if a lamp is "on" in a DC circuit, and the diode in series with the lamp is reversed, the light will be turnned off due to the diode blocking current flow (unless the voltage is above the breakdown voltage of the diode - if this is the case, the diode will fail). If this is an AC circuit, every half cycle the diode will turn on, then the next half cycle it will turn off. To your eye, the bulb will most likely appear slightly dim due to this on then off cycling. If the diode is reversed, there will be no apparent change. The difference is the half cycle the diode would have been off before reversing, it will now be on, etc.
A A diode has two state either on [forward conduction .7 volts. Or reversed bias meaning the diode voltage polarity are revered or cut off, depends on the diode but it will leak some current , Anyhow that is reversed bias diode conditionForward conduction voltage can vary between about 0.6 volts and about 1.4 volts depending on the diode and the current. Also, some diodes, such as zener diodes, will conduct in the reverse direction. Reverse bias is simply where the anode is more negative than the cathode.
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.
