Light Emitting Diodes are devices that are mostly used as indicators and for lighting purposes ,and that,just because they can emit light!In this article we cover what they are and go through different scenarios of using those versatile devices.The goal is to show that the simple and yet powerful basic concepts of electronics covered so far can be used to realistic and meaningful ends.Enough talk,lets get our hands dirty!Continue reading
We already have a considerable amount of information about circuit configurations.We can build and analyze Series and Parallel circuits. In this article we analyze a more practical configuration you are most likely to run into in your daily life as an electric circuit designer, implementator and troubleshooter.Ladies and gentlemen let me introduce you to the Series-Parallel circuit configuration!Continue reading
This post has a concept enforcing video that can be found here.
In a previous article on Ohm’s Law,we have made clear the relationship between voltage,current and resistance . In this article,we want to scale up;not just use ohm’s law to analyze a single resistor circuit but to attack circuits with even multiple resistors.Resistors are connected in very interestingContinue reading
Energy is defined as the ability to do work.There are many ways we can make sense of this statement.For example,when current passes through a resistor,heat is generated.This heat can be used in winter to heat up our rooms ,or in our kitchens for cooking purposes;this is work being done !Continue reading
Ohm’s law gives us a way to mathematically relate voltage,current and resistance.This is important since it allows us to determine an unknown quantity from those we already know or can easily measure. Ohm’s law states thatContinue reading
