Ohms Law Explained - The basics circuit theory

[Applause] hey there guys Paul here from the engineering mindset calm in this video we're going to be looking at Ohm's law to understand how it works as well as how to use it there are also two problems at the end of this video for you to test your knowledge and see if you can solve so what is Ohm's law Ohm's

law is a relationship between voltage current and resistance and how they relate to each other Ohm's law was developed by German physicist named Georg ohm who undertook many experiments to develop his theory including measuring current by touching live electrical circuits to see how much it hurt as you might imagine the higher the current the more it hurt now there

are three formulas we need to use for Ohm's law but we don't actually need to remember these and I'll show you a super easy tip in just a moment so the three formulas we use for Ohm's law are voltage equals current multiplied by resistance current equals voltage divided by resistance and resistance equals voltage divided by current if

that seems like a lot to remember then don't worry because we don't need to remember them all we need to remember is Ohm's triangle which looks like this so you just need to remember these three letters in order V I R then we just write those letters in a triangle with V at the top and we draw a line to

separate the letters in fact you don't even need to remember those because I've made a free pdf guide for you with some worked examples but you can keep on your PC or your mobile and access wherever you need links for that can be found in the video description down below now all we do when we need to use a formula is
