Only because the circuit that its embeded in is designed that way.

Remember, a transistor is basicly an amplifier ...

only if you design everything to go to the extreams will it act as a switch.

What is the function of an AC transistor in electronic circuits?

An AC transistor in electronic circuits is used to amplify and control the flow of alternating current (AC) signals. It acts as a switch or amplifier to regulate the voltage and current in the circuit, allowing for the manipulation and processing of AC signals for various applications.


Is transistor linear or non linear?

A transistor can function in both linear and non-linear modes. In the linear mode, it can amplify small signals with a linear relationship between input and output. In the non-linear mode, the transistor operates as a switch, turning on or off based on the input signal.


What the difference between Transistor and resistor?

A transistor is a semiconductor device used to amplify or switch electronic signals, while a resistor is an electrical component that resists the flow of current in a circuit, thereby controlling the amount of current. Transistors are active components that can amplify signals, while resistors are passive components that mainly control the current and voltage levels in a circuit.


What component is used to turn the current on and off?

A transistor is commonly used to turn the current on and off in electronic circuits. By applying a small input signal to the transistor, it can control the flow of current between its terminals, effectively acting as a switch.


Howdoes transister work as aswitch?

A transistor can act as a switch by controlling the flow of current between its two terminals. When a small amount of current is applied to the base terminal, it allows a larger current to flow between the other two terminals (collector and emitter), effectively turning the transistor on. When no current is applied to the base terminal, the transistor is turned off and no current flows between the collector and emitter terminals. This on/off behavior allows transistors to function as switches in electronic circuits.

How does a transistor electronically switch the output on?

A transistor can electronically switch the output by controlling the flow of current between its two terminals, called the collector and emitter. It has a third terminal, called the base, which acts as a control input. When a small current is applied to the base terminal, it influences the flow of current between the collector and emitter terminals, effectively turning the transistor "on" or "off" and allowing it to change the output state.
