Is scr current controlled device?
yes it is current controlled
What is the Difference between voltage controlled device and current controlled device?
The difference between a current control device and voltage controlled device is that for current controlled device, the current is constant and the voltage is variable while for a voltage controlled device, the voltage is constant and the current is variable.
Is thyristor a current controlled or voltage control device?
Triac is the current control device.
Is BJT is a current control device or voltage control device?
transistor is a current controlled device. as the current flows through the base of the transistor , it works like a close switch.
Why bjt is called current controlled current device?
Because the operation of the transistor is determined by the current at the base. the principle equations of BJT operation are: Ic = h*Ib ,and Ie=Ib+Ic thus device operation is controlled by the input current.
What are current controllable devices?
BJT is a example for current controll device. And JFET is a voltage controlled device.
Is scr current controlled device?
yes it is current controlled
What is the Difference between voltage controlled device and current controlled device?
The difference between a current control device and voltage controlled device is that for current controlled device, the current is constant and the voltage is variable while for a voltage controlled device, the voltage is constant and the current is variable.
Why Silicon Controlled Rectifier is called current controlled device?
Because it is controlled by the gate current
Is thyristor a current controlled or voltage control device?
Triac is the current control device.
What do you mean by a current controlled device?
It is modeled as a 2-port "black box", where the input terminals accept a current (and are modeled by 'zero' resistance to that current), and the output is a function of the input current. the output may be a voltage or current (or other varying physical parameter, such as resistance). A bipolar transistor is well modeled as a current controlled device. The collector (output) current is a function of the base current: Ic = Beta * Ib. The hybrid-pi model changes that from a current controlled device to a voltage controlled device: Ic = F(Vbe), but the BJT transistor is still basically a current controlled device.
Why ujt called current controlled negative resistance device?
The On/OFF action in UJT is controlled by emitter current
Example of a DC current device?
a typical example of a d.c current device is a generator it supplies current directly to houses
What are passive electronics?
Answeractive device : they are the devices in which the electron flow( current) can be controlled electrically else a device with controlling of current flowPassive device : they are the device where electron flow ( current ) cannot be controlled electricallyelse a device with out controlling otion of current flowI studied the above from net and i felt it is correctany new definition (more appropriate) are welcome
Why FET called current controlled device?
BJT is a current controlled device because its output current is dependent upon the current in the base while for FET it is controlled by the voltage at the gate terminal of the transistor. BJT is a current controlled device because its base current is not zero while for a FET the gate current is zero
Is BJT is a current control device or voltage control device?
transistor is a current controlled device. as the current flows through the base of the transistor , it works like a close switch.
What is the difference between a switching transistor and an ordinary transistor?
In the switching transistor the output current is controlled by the (current) and this is also called current controlled current device (CCCD). But in ordinary switch we controlled output current physically...
