Resistor

From TheBestCaseScenario

A resistor is an electronic part that impedes current flow in a purely resistive way :) That means it will make it harder for all kinds of current to pass through it, while converting the lost energy into heat.

Resistors are made in several ways, the most common being by making a long thin, wire into a coil, then covering it with ceramics. This will give you the regular, capsule looking resistor. Another method is by depositing a thin film of a material that is more resistive to current flow on a surface, equip it with some small legs/pins and have current flow through it. This method is used to make integrated or small, surface mounted device resistors, used in and near chips.

They are basic building blocks that are very used and very useful. With them you can 'tell' passive or active devices what to do and how to do it, so they influence quality and quantity in an electric/electronic circuit. They not only impede current flow, but through all kinds of mathematical and physics equation.. and trial and error.. have been found to have 'magical' properties, when linked with capacitors, coils or other resistors and integrated chips or transistors.
