We know that one of the main uses of resistor is to control the flow of current. In a resistor, electrons have a collision with ions which slows down the flow of electricity and lowers the current and also produces heat. If a resistor is said to have high resistance then it means less current flows in it for the given voltage.
Some applications and uses of resistor are listed below:
There are various types of resistors that work according to the usage range. In that, we can set the resistance by using a knob kind of feature. Changing resistance will affect the flow of current inside the circuit. For example, this type of resistor is used in controlling the speed of a motor, pitch of a musical tone, loudness of an amplifier, etc.
Dividing the voltage works when some components need to work in a much lesser voltage than the supplied input voltage. Connecting the resistors in a series will help to drop the voltage across each resistor equally, thus, assisting the appliances smoothly which works in those conditions.
Because of the nature of generating heat when conducting current, resistors are used in a heater, toaster, microwave, electric stove, and many more heating appliances. In a light bulb, the metal filament glows white-hot due to the very high temperature produced from the resistance when electricity is passed through it.
Like in a light flasher, electronic sirens, blinking lights used in airplanes or tall towers which acts as a collision avoidance measure. They work on the principle of filling up current to a certain time and then discharge light, in here, the resistor decides how much current has to be passed according to the time allotted. If resistance increases, the time for discharging current in the circuit increases.
Too much current passed inside a LED or transistors can be dangerous because they are very sensitive to electric current. The use of a resistor in the circuit will help the LEDs and transistors and other types of semiconductors to function in the desired current range ideal for them.

Frequently Asked Questions – FAQs
Q1
What is a resistor?
A resistor is a two-terminal electrical component that provides electrical resistance. In electronic circuits, resistors are predominantly used to lower the flow of current, divide voltages, block transmission signals, and bias active elements.
Q2
What are the two types of linear resistors?
Fixed resistors and variable resistors are the two types of linear resistors.
Q3
What are the main types of fixed resistorstypes of fixed resistors?
Wire wound resistors, thin-film resistors, and carbon composition resistors are the main types of fixed resistors.
Q4
What are the main types of variable resistors?
Potentiometer, thermostat, and trimmer resistor are the main types of variable resistors.
Q5
What is the use of resistors in the case circuits with LEDs?
Excess current can be fatal to LEDs because they are extremely sensitive to variations in electric current. In this case, resistors can be used to control the electric current that flows through the circuit, helping LEDs and other semiconductors to work at the ideal current ranges.
There is a broad range of resistors. In order to know the position of ROHM's resistors, we have attempted to classify not only based on the general materials used, but also in terms of the shape, integration level, and functions.
This is the classification based on the functions of the resistors. The classification is made as fixed resistors and variable resistors, and, normally, the word "resistor" implies a fixed resistor.
Variable Resistors:
Variable resistors are composed of a fixed resistor element and a slider which taps onto the main resistor element. This gives three connections to the component: the fixed resistor element, the main resistor element, and the slider. Because of this, the component acts as a variable potential divider for all three connections that are being used. If variable resistance is desired, It is possible to connect to the slider on one end.
Fixed Resistors:
The most widely used type of resistor is the fixed resistor. They are used in electronics circuits to set the conditions for a circuit. During the design phase their values are determined, which from then on. they should never need to be changed to "adjust" the circuit.
Most fixed resistors use thin film technology and are of the surface mount type. As these are used in their billions these days, this makes this form of resistor technology one of the most widely used.
The figures above show the cross-sectional views of surface mounted type resistors.
