1. Resistance (components of the circuit board)

We use resistors regularly in most PCB projects, and most of us are familiar with their functions; Resistors are one of the most commonly used components on a circuit board, they are very popular and fairly easy to use. The flow of electricity… Thus, resistors help dissipate electrical energy in the form of heat. There are several types of resistors, the classification methods are also different, and the materials used for making resistors are often different, because we use different materials for different purposes.

Another different way of resistors is the way the wire is led out, and in this regard, the most common type is the axial resistor. Electronics enthusiasts, beginners, and hobbyists often like to use axial resistors because they are easy to integrate into any circuit. Each resistor has rings around it, these rings are a color code indicating the resistance value of that particular resistor, and these rings also tell us about the possible tolerances of the resistor.

2. Capacitors (components of the circuit board)

After resistors, capacitors are probably the most common component on a circuit board, and capacitors are also the first choice for PCB enthusiasts. However, we use fewer capacitors than resistors. The basic function of a capacitor is to store charge in it, a capacitor consists of two metal plates with a dielectric between the two metal plates, the two plates store opposite charges, and the dielectric helps to separate them. In this way, current begins to flow through the circuit.

Capacitors are classified in a variety of ways. However, we mainly classify capacitors according to their dielectric material. This is because the dielectric material is responsible for giving the capacitor key characteristics; The denser the dielectric material, the more charge the capacitor can store on its plate; This is why we tend to use high-quality materials to make capacitors in order to obtain higher capacitance… A typical capacitor has two wires sticking out of a metal plate… We use these lines to integrate the capacitor into the circuit.
