Electronic Components - The Resistor
Electronic Components - The Resistor Part II
What is a resistor? It is component that can resist or limit the flow of current. Apart from resistors, other electronic components also exhibit an amount of resistance, however the precise amount can vary. The unit of measure of resistance is the Ohm (Ω), and named after the clever German physicist Georg Simon Ohm. He discovered that there was a relationship between voltage (the amount force that would drive a current between two points), current (the rate of flow of an electric charge) and resistance (the measure of opposition to a current) – what we know as Ohm’s law – which states that the current between two points in a conductor is directly proportional to the potential difference (voltage) between the two points, and inversely proportional to the resistance between them. more (Follow link: read and take notes)...
Today we continue with the series of articles on basic electronics with this continuation of the article about the resistor. Part one can be found here.
With regards to this article, it is only concerned with direct current (DC) circuits.
In this chapter we will examine how two or more resistors alter the flow of current in various ways. First of all, let’s recap what we learned in the previous chapter. more (Follow link: read and take notes)...
