What is the purpose of using a resistor in a circuit?
A resistor is a passive electrical component with the primary function to limit the flow of electric current.
What is the function of resistor transistor?
The role of the collector resistor is to convert the collector current into voltage; its resistance is chosen high enough to saturate the transistor and low enough to obtain low output resistance (high fan-out).
Why do we put resistor on base of transistor?
With the input low, the output of the internal NOT gate is high, which pulls high (and turns on) the internal NPN transistor, creating a low-impedance path from the output pin to ground. “base” resistor, so called because it limits the amount of current that flows through the base of the transistor.
Can we use BJT as a resistor?
This is because collector and emitter cannot be exchanged without a drastic change in voltage-current characteristic. More than that, for Vce=0 the current Ic does not cross the origin for any finite control voltage Vbe. Hence, the BJT cannot be used as avoltage-controlled resistor.
Why resistor is used in snubber circuit?
Why resistor is used in Snubber circuit? To minimize the loss . To minimize the charging current. Snubber circuit is used in parallel with SCR to limit high dV / dt across the SCR.
What is the primary role of a resistor in a circuit How does it affect the electricity being supplied in the circuit?
When used in series, resistors can be said to be a “voltage dividing network.” This is because in a series circuit, current flowing through each resistor is the same value but the voltage present across each resistor is only part of the total circuit voltage value.
What’s the difference between a resistor and a transistor?
Transistor: A transistor is an electronic device used to control the flow of an electric current. Resistance: The resistor is an electronic component that limits or limits the current flow and divides the voltage in an electronic circuit. Its main purpose is to provide a precise amount of electrical resistance.
Can you use a transistor without a resistor?
Some transistors that have internal series base resistors so that they can be turned on and off with control voltages without an external resistor. Such resistors are unusual, but they are exist.
What is the function of BJT?
The main basic function of a BJT is to amplify current it will allow BJTs are used as amplifiers or switches to produce wide applicability in electronic equipment include mobile phones, industrial control, television, and radio transmitters. There are two different types of BJTs are available, they are NPN and PNP.
