Introduction to Electronic Devices
Electronic components are among the most fundamental components of electronic circuits. They are discrete or physical objects that control electrons and magnetic fields. The components can be divided into two types: passive and active components. Active components, such as integrated circuits and transistors, require an external power source to function and operate, whereas passive components, such as capacitors and resistors, do not.
Knowing the different types of electronic parts is crucial for anyone involved in creating or managing electronic devices. Each element has a particular function and is an integral part of the function and functionality of the whole technology.
Resistors
Resistors are one of the most essential components of electronic circuits. They are utilized to limit the flow of electricity that regulates the current and voltage in circuits. Resistors can be found in many applications, such as the restriction of current, the division of voltage, and the processing of signals.
Types of Resistors
Fixed resistances are made by using the invariable resistor.
Variable Resistors are Also called potentiometers. They allow the modification in resistance.
