Which terminal of a bipolar transistor has the current direction arrow?
The emitter
What is an ir emitter?
Depending on context, it could be an infra-red emitter. An emitter that emits at a wavelength longer than that of visible red. infra red emitter is a special pn juction device in which emitter region emits infrared rays
In a common emitter transistor the primary purpose of a resistor connected to the emitter is to?
The emitter resistor in a common emitter configuration provides negative feedback to the transistor, reducing both its voltage gain and distortion.
When an NPN transistor is properly biased then most of the electrons from the emitter -?
Emitter
Why is collector current slightly less than emitter?
The percentage of doping in emitter is higher than collector region.hence large current is flow to emitter than collector.
Which terminal of a bipolar transistor has the current direction arrow?
The emitter
What is the indication of arrow heap in the transistor?
it indicates the direction of flow of emitter current
Why emitter current flows away from base in NPN transistor?
arrows are shown for conventional current, not electron current.
Why ujt have this type of symbols?
The symbols in the unijunction transistor show its internal configuration. The emitter (arrow) represents the polarity. When it points in that is a P type transistor. Pointing out is an N type. The the table on its side the table top touching the emitter (arrow). Its' "legs" are the connection to two bases in the device. It does not have a collector. Refer to another Wiki answer for more info.
How is benchmark shown on a map?
A bench mark is shown as an upward pointing arrow with a bar above the point.
How a vector represent distance and direction?
A vector is like an arrow. The length of the vector represents the magnitude (distance, speed, whatever) while the direction is shown by the direction of the arrow.A vector is like an arrow.

What is transistor action?
The transistor has three regions, emitter,base and collector. The base is much thinner than the emitter while the collector is wider than both. However for the sake of convenience the emitter and collector are usually shown to be of equal size. The transistor has two pn junctions that means it is like two diodes. The junction between emitter and base may be called emitter-base diode or simply the emitter diode.The junction between base and collector may be called collector-base diode or simply collector diode. The emitter diode is always forward biased and the collector diode is always reverse biased.
Why base in grounded in common emitter transistor as amplifier?
With a common emitter amplifier it's the emitter that is usually grounded.
What is emitter follower?
A: When a signal is not amplified but simply taken from an emitter the reason is that the emitter will provide better current capabilities
What is an ir emitter?
Depending on context, it could be an infra-red emitter. An emitter that emits at a wavelength longer than that of visible red. infra red emitter is a special pn juction device in which emitter region emits infrared rays
What is the arrow to the left of north on a compass?
The symbol that shows direction with an arrow towards North with the letter 'N' (for North) is called a north arrow. It is mostly shown in a cruciform (in the form of a cross)
What is the difference between a CB amplifier and CE and emitter-follower?
I think you mean a common emitter amplifier, which is an amplifier of voltage. Emitter-follower or common collector amplifiers are used to match impedances, or to amplify power or current. The emitter-follower is a type of common emitter circuit that has a resistor between the emitter and ground. The output signal is taken from the point between the emitter and its resistor.
