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.

How did the word transistor originate?
The word "transistor" is a blend of "transfer" and "resistor," reflecting its function of transferring electrical signals across a resistor. It was coined by John R. Pierce, an engineer at Bell Laboratories, where the first transistor was developed in 1947.
What is the difference between a bipolar transistor and a field effect transistor?
A bipolar transistor uses both majority and minority charge carriers for conduction, while a field effect transistor primarily relies on majority charge carriers. Field effect transistors have a higher input impedance compared to bipolar transistors. Additionally, bipolar transistors are current-operated devices, while field effect transistors are voltage-operated devices.
Potential difference across resistor is doubled?
If the potential difference across a resistor is doubled, the current flowing through the resistor will also double, assuming its resistance remains constant. This relationship is described by Ohm's Law, where current is directly proportional to voltage when resistance is held constant.
What is the difference between resistance box rheostat and resistor?
A resistance box is a device that contains a set of fixed resistors that can be connected in various combinations to achieve different resistance values. A rheostat is a variable resistor that can be adjusted to change the resistance in a circuit. A resistor is a general term for a component that resists the flow of electrical current in a circuit and comes in fixed resistance values.
What is the difference between resistor and insulator?
A resistor is a component that limits the flow of electric current in a circuit, while an insulator is a material that restricts the flow of electricity. Resistors are used to control the amount of current in a circuit, whereas insulators are used to prevent the flow of electricity altogether.
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.
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
Difference between variable resistor and rheostat?
The difference between a variable resistor and a rheostat is the same as the difference between six and half a dozen.
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.
