Guide for Tech Beginners - Resistor

Resistor is an electric component which resists the flow of electron. Resistor is a very basic and most common circuit element. We use resistor to control the current flow in an electric circuit. Controlling current is very important and electronic engineering is nothing but an art of controlling current. You can not find any electric device or circuit without resistor. Resistors are passive components, meaning they only consume power (and can’t generate it). Resistors are usually added to circuits where they complement active components like op-amps, microcontrollers, and other integrated circuits. Commonly resistors are used to limit current, divide voltages, and pull-up...
