Types of Resistor
Fixed Resistors
Resistors with resistance that doesn’t change with any change in the temperature or voltage may be termed fixed resistors. These resistors are available in different sizes and shapes. Any resistor providing constant resistance in different environments is considered an ideal fixed resistor.
Variable Resistors
A resistor whose electric resistance value may be adjusted is termed a variable resistor. It may be considered as an electromechanical transducer which generally works by a sliding wiper over the resistive element. A potentiometer is a variable resistor used as a potential divider by bringing in use 3 terminals.
Metal Film Resistor
A metal film resistor or a carbon film resistor is constructed as a result of the deposition of a thin film constituted of a conductive material such as a metal or pure carbon on an insulating core.
Light Dependent Resistor
An LDR or light-dependent resistor varies in resistance depending on its intensity of falling light. It is made up of cadmium sulfide which comprises a few electrons when it is not illuminated.
Non-Linear Resistor
Non-linear resistors or varistors are popular for having the characteristic curve which is a non-linear V-I. Its resistance is neither uniform nor it obeys the ohms law. These are made up of materials consisting of zinc oxide and silicon carbides. These are generally divided into three types which are silicon carbide disc type varistor, silicon carbide rod type varistor, and zinc oxide type varistor.
Thermistor
Thermistor refers to a thermal resistor. The resistance value of these resistors changes with the temperature change. Mostly, thermistors are known for having a negative temperature coefficient which means that there is a downfall in their resistance with the increase in temperature.
Characteristics of Resistors

Resistance (R)
Resistance is the primary characteristic of a resistor, measured in ohms (Ω). It quantifies how strongly the resistor opposes the flow of electrical current. A higher resistance value indicates greater opposition to the current flow.

Power Rating (P)
The power rating (P) of a resistor specifies the maximum amount of power, measured in watts (W), that it can safely dissipate without overheating or sustaining damage. Hence, choosing an appropriate power rating is crucial for circuit safety and reliability.

Tolerance
Tolerance refers to the permissible deviation in the actual resistance value from the specified value. It is typically expressed as a percentage (±1%, ±5%, etc.). Resistors with lower tolerance values are more precise and are essential in circuits where accuracy is critical, such as measurement and calibration circuits.

Temperature Coefficient
The temperature coefficient indicates how much a resistor's resistance changes in response to temperature fluctuations. This is a critical consideration for applications where the resistor might experience significant temperature variations, such as in automotive electronics or industrial control systems.
How Resistors Work
Resistors function by converting electrical energy into heat. When current flows through a resistor, some of the electrical energy is transformed into heat due to collisions between electrons and the atoms in the resistor material. This process, known as Joule heating, is the fundamental principle behind how resistors limit current flow. The amount of heat generated is proportional to the square of the current and the resistance value.
Ohm's Law (V = I × R) describes the relationship between voltage (V), current (I), and resistance (R). This law is fundamental to understanding and designing circuits with resistors. By applying Ohm's Law, you can calculate the appropriate resistor value needed to achieve a desired current flow or voltage drop within a circuit.
