there is 2 types of componant
1-passive compnant:who provide a fixed voltage to active componant we can not use them in rectification or amplification,registor,capacitor,inductor
2-active componant:we can use its as a amplifier r rectifier,diode,transistor,scr,etc
(we can use registor for voltage drop,so it is passive componant)

∙ 8y agoA resistor is considered a passive device and has two terminals and nominally fixed resistance.
A transistor is considered an active device and has three terminals. One terminal is a control terminal and appropriately driving that terminal will affect the apparent resistance between the other two. Hence the term "semiconductor".
As a result, the resistor has a fixed restriction on the current flow within the device, the amount depending upon the fixed resistance value, R. The current that flows = V/R.
In the transistor, the amount of restriction is able to be modulated (by the base current of a BJT or the gate voltage of a MOSFET) using the third terminal and therefore it becomes an active control device.

How do you bias a 2N5777 photo-transistor?
connect the base of the transistor to a variable resistor and to a normal resistor
What is rt in electronics?
I believe that is resistor transistor technology TTL transistor transistor logic
Why transistor is called transfer of resistor?
Transistor=Transfer+Resistor. When Transistor operates in active region its input resistance is high and output resistance is low. So,We can consider transistor as a device which transfers its resistance from high to low. And by this property transistor amplifies input signal.
How to draw NOT gate using NPN transistor?
RTL logic: NPN transistor. Emitter grounded. Input connected to base through a resistor. Vcc also connected to base through a resistor. If the input is high or open, the transistor is on. If the input is low, the transistor is off. Connect a resistor from Vcc to the collector. The collector is the ouput. You have to play around with resistor values to setup your fan-in and fan-out properties.
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.
Why transistor so named?
Transistor stands for "Transfer Resistor". (Resistor of transference)
What is the full form of transistor?
The fullform of transistor is transfer resistor.
What the difference between Transistor and resistor?
The difference between a Transistor and a Resistor is that a transistor is designed to amplify the electrical current, whereas a Resistor is designed to reduce the electrical current.
How do you bias a 2N5777 photo transistor?
connect the base of the transistor to a variable resistor and to a normal resistor
How do you bias a 2N5777 photo-transistor?
connect the base of the transistor to a variable resistor and to a normal resistor
What is self biasing a transistor?
if a transistor resistor is connected to the emmiter .
Can a transistor can act like resistor capacitor inductor?
A transistor acts like a resistor when Gate is connected to Source.
What is rt in electronics?
I believe that is resistor transistor technology TTL transistor transistor logic
Function of resistor capacitor and transistor on integrated circuit?
resistor
Are transistor the same as the variable resistor?
no
Why is a resistor positioned before the transistor?
It is done in order to protect the transistor from the heavy currents flowing (resistor reduces current flow) into its terminals.
Why transistor is called transfer of resistor?
Transistor=Transfer+Resistor. When Transistor operates in active region its input resistance is high and output resistance is low. So,We can consider transistor as a device which transfers its resistance from high to low. And by this property transistor amplifies input signal.
