Which terminal of a bipolar transistor has the current direction arrow?
The emitter
Why the arrow mark in emitter is base in ujt?
In a Unijunction Transistor (UJT), the arrow mark in the emitter symbol indicates the direction of conventional current flow when the device is forward-biased. The emitter (E) is the terminal where current flows out, and its arrow points toward the base region, which is the junction where the UJT operates. This configuration helps identify the emitter as the terminal that controls the device's operation, distinguishing it from the base and preventing confusion in circuit diagrams.
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

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.
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.
What are forces shown as?
Forces are typically shown as vectors in physics, with an arrow representing the direction of the force and the length of the arrow indicating the magnitude of the force. This helps to visually represent how forces act on objects in a particular direction.
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
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 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 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
