Actual meaning of transistor transfer the resistance

In summary, a transistor is a device that transfers current from a low resistance circuit to a high resistance circuit, which is known as impedance matching. This is often used to drive a circuit with high power using a circuit with low power. For more information, check out the Wikipedia page on impedance matching.

it is given as "the concept of transferring the current fron low resistance to high resistance circuit is one version of transfer of resistance".
its about transistor.

the complicated answer is that's its complicated
http://en.wikipedia.org/wiki/Impedance_matching

the simple answer is that if you want to drive a circuit that requires high power with a circuit that only has low power then obviously you will want to use a transistor to up the power

1. What is the purpose of a transistor?

A transistor is an electronic device that is used to amplify or switch electronic signals. It is a fundamental building block of modern electronics and is used in a variety of devices such as computers, televisions, and cell phones.

2. How does a transistor transfer resistance?

A transistor works by controlling the flow of electrons between two terminals, known as the collector and emitter, by using a third terminal called the base. This control is achieved by varying the amount of current that flows through the base, which in turn affects the resistance between the collector and emitter.

3. What is the difference between a bipolar and a field-effect transistor?

A bipolar transistor uses both electrons and holes to conduct current, while a field-effect transistor uses only one type of charge carrier (either electrons or holes) to control the flow of current. This results in different characteristics and applications for each type of transistor.

4. How does a transistor amplify a signal?

When a small current is applied to the base terminal of a transistor, it allows a larger current to flow between the collector and emitter terminals. This amplification is achieved through the use of multiple transistors connected in a circuit, allowing for a larger overall signal amplification.

5. What are some common applications of transistors?

Transistors are used in a wide range of electronic devices, including computers, televisions, radios, and cell phones. They are also used in power supplies, motor control, and sensors. In general, transistors are essential components in any electronic system that requires signal amplification or switching.
