What is a swift current that flows away from the beach?
Rip current affect the shape of theass
How does a semiconductor work?
we know that in a transistor we have three types of regions: EMITTER, COLLECTOR, BASE, and we know that emitter is highly doped, so charge carriers are very high, so resistance is very less, and on the other side collector is moderately doped so charge carriers are less, so resistance is very high. So from the above concept we conclude that in a transistor current is flowing from low resistance to high resistance. for example the 100 electrons are moving from emitter to base, in base only some (4 electrons) of the electrons are neutralized, and remaining 96 electrons are moved to collector terminal through high resistance path. so now same current flowing through high resistance so voltage amplified.
What is a conventional current?
Conventional current shows current flow from + to - amp meters are labeled this way (conventional current flow) (hole flow) Physics shows that electrons are moving or flowing from - to + (electron flow) Tubes (deforest valves) sort of blew conventional current away semiconductors with different doping materials confuse it more so most new books relate to electron flow voltmeters ammeters are labeled the same since the 18th century
In what ways are Oedipus stage actions consistent with his prior actions?
Oedipus' only motivation in his prior actions was to get away from his prophecy. His current actions were the result of wanting to get rid of the plague.
Are some of the people that died during the titanic still under water?
yes, they couldn't get everyone out, plus with the current, they might been swept away from where the Titanic actually sunk.
How can you identify the emitter of transistor SL100?
The SL100 transistor has a TO-39 case. In the TO-39, the emitter is closest to the tab, and the collector is furthest away from the tab.
Why two diode join cant act as transistor?
No, it is not possible because in transistor the depletion layers formed in Emitter-Base Junction & Collector-Base Junction are penetrable by both current carriers but in this case of two diodes; the formed depletion region are not penetrable for current carriers (hole &electron). Also, a transistor works only because the base layer is very thin. You won't get that thin layer between emitter and collector just by connecting two diodes together. This thin base layer places the Emitter and Collector in very close proximity to each other. This allows majority carriers from the emitter to diffuse as minority carriers through the base into the depletion region of the base-collector junction, where the strong electric field collects them. In other words the emitter/base current flow draws some of the barrier charge away from the collector/base junction and allows collector/emitter current to flow across the base using minority carriers. So transistor action is not possible. But we can make transistor by connecting two diodes and two dependent current sources i.e. Ebers-Moll model of transistor. This is true only when you want to make the transistor act like a on/off switch, but you cannot make this setup of diodes to act like an amplifier. Whereas the transistor also acts as an amplifier too A transistor can act as: (1) on/off switch (2) amplifier. Diode is made up of two layers and one junction. Transistor is made up of three layers and two junctions.
Why arrow is shown at emitter?
To indicate direction of flow of the substance being carried and distributed by that emitter. For example, plumbing parts often indicate direction of flow of the water or gas so that the parts function properly.
Strong surface current that flows away from the beach?
rip current.
What is a swift current that flows away from the beach?
Rip current affect the shape of theass
Which direction does the California current flow?
It flows from the north, where it's cold, to the south.
What is saturation and active region in a transistor?
The output current of a transistor is controlled by the current in the 'base' input: Increasing the control current will increase the output current in a more or less linear fashion. In the saturation region, this is no longer true: The transistor is nearing the limits of how much current it can conduct, so increasing the control current further has little or no effect. When using a transistor as an amplifier, you want to stay away from the saturation region as it would distort the signal you are amplifying. When using a transistor as an on/off switch, as in digital circuits, being in the saturated region is 'on' and a normal mode of operation.
How do you find emitter base collector terminals in transistor?
I know only two types of transistors, one is with a metal head, another one with a plastic covering. For the metal one, you could see a little protruding metal piece, the pin near it is EMITTER, the one which is away from that is COLLECTOR and the other is BASE For the plastic one, one face of it will be flat, make it lie down such that the flat side is touching the ground, now the middle one is BASE, right one is COLLECTOR, left one is EMITTER For all others where both the sides are flat, check for a dot or circle on it, place the transistor so that you the dot or circle faces you, now the middle one is BASE, right one is COLLECTOR and the other is EMITTER
What is a long shore current?
A long shore current is sometimes flows along the shore and it also pull people away from the place where they entered the water
What is the difference between power transistor and power mosfet?
A BJT is one type of transistor and POWER TRANSISTOR can be BJT or MOSFET or some other phenomena.POWER TRANSISTOR are usually those who are used at high current ratings e.g at POWER AMPLIFIER where large transistors are used at final stage to gain output.

What is thermal run away in bipolar transistors?
A "thermal runaway" occurs when a transistor is heated to such a point, that the more heat it has, the quicker it will accumulate it. This usually involves leakage current which typically increases with temperature, and which causes more current to flow - which increases the heat buildup in the transistor more, and the cycle continues. This heat buildup rapidly accelerates, and it invariably and quickly (in a matter of seconds or quicker) burns out the transistor as it reaches temperatures it was not meant to safely handle.
