What technology was the first step towards electronic miniaturization?
The transistor was the invention that allowed electronics to move away from the use of vacuum tubes (also called valves).
How an n-p-n transistor can be used as a switch?
An n-p-n transistor can be used as a switch by controlling the current flowing through its base terminal. When a small current is applied to the base, it allows a larger current to flow from the collector to the emitter, turning the transistor "on." Conversely, when the base current is removed, the transistor turns "off," stopping the current flow. This on-off control allows the n-p-n transistor to effectively switch electrical circuits.
Bc stands fo what in transistor?
base to collector
What is a vacuum tube used for?
The same things a transistor is used for.

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.
Why RC couple is called transistor?
Its not!
Why transistor so named?
Transistor stands for "Transfer Resistor". (Resistor of transference)
Why transistor is called as bi-polar device?
Transistor is called Bi-Polar device because the current can be flow due to electron and holes, hence it is called bipolar.
Why pnp transistor is called so?
The types of dopant used are: p-type, n-type, p-type respectively.
What is unmodulated signal from a transistor is called?
When the out from a transistor is the exact replic of the input signal then it is called unmodulated signal i e. there will not be any change in frequency voltage power etc
Why a transistor is used as a amplifier and switch?
transistor has 2 output 1 and 0 so can be used as a switch
What can the input of a transistor be called?
The input of a transistor is typically referred to as the "gate" in a field-effect transistor (FET) or the "base" in a bipolar junction transistor (BJT). In both cases, the input controls the flow of current through the transistor, allowing it to function as a switch or amplifier in electronic circuits. The gate or base receives the input signal that modulates the transistor's operation.
Why a transistor is called with BC547?
A small signal NPN transistor used for general purpose audio amplifiers and switching.
What are transistor connections called?
Transistor connections are commonly referred to as terminals. For bipolar junction transistors (BJTs), the three terminals are called the emitter, base, and collector. In field-effect transistors (FETs), the terminals are called the source, gate, and drain. These connections are essential for the transistor's operation in amplifying or switching electronic signals.
What is emitter biasing?
Emitter biasing is when you add a resistor between the emitter of a transistor and the 0v rail so that any voltage developed across the emitter will subtract from the voltage on the base and effectively turn the transistor OFF. We are talking about an NPN transistor and the transistor is an "ordinary transistor" or BJT (bi-polar Junction Transistor). For more information on transistor biasing see: Talking Electronics website.
Why is MOSFET called IGFET?
MOSFET is Metal Oxide Semiconductor Field Effect Transistor. IGFET Insulated Gate Field Effect Transistor. But these expressions are practically synonyms.
