## 8.02x – Lect 9 – Electric Currents, Resistivity, Conductivity, Ohm’s Law

When positive charges move in this direction, then, per definition we say the current goes in this direction. When negative charges go in this direction, we also say the current goes in this direction, that’s just our convention. If I apply a potential difference over a conductor, then I’m going to create an electric field […]

## Voltage and current relation, Ohm’s law use in Hindi

Today, I will explain, If voltage increases, then current will increase, or decrease, or will remain same, Many persons ask me, in some videos, you tell current will increase, In other video, you tell that current will decrease, so I will tell today, where will current increase, and where will current decrease, Here, A load […]

## Ohm’s Law | #aumsum

Ohm’s Law Welcome to the Tribute to Scientists Association. Presenting, Sir Georg Simon Ohm. Let us study his law. German physicist Georg Simon Ohm stated that the electric current flowing through a metallic wire is directly proportional to the potential difference across its ends, provided its temperature remains the same. This law is called Ohm’s […]

## Basic Electricity – Resistance and Ohm’s law

In this video I’m going to talk about electrical resistance, ohm’s law, and how to pick a resistor to limit current in an LED circuit. In previous videos I talked about how voltage can behave like a pushing force, pushing electric current around a circuit. But in one example I connected an LED straight to […]

## Ohms Law Explained – The basics circuit theory

– Hey there guys, Paul here from theengineeringmindset.com 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, […]

## Ohm’s Law – MeitY OLabs

Ohm’s Law Our aim is to determine the resistance per centimeter of a given wire by plotting a graph of potential difference versus current, and hence to determine its resistivity. To do the experiment, we require the following: screw gauge, battery, one way key, rheostat, voltmeter, ammeter, measuring scale and resistance wire. Connect the positive […]

## Resistors – Ohm’s Law is not a real law

Ohm’s Law is one of the most basic principles in electronics, yet it is not an actual physical law. Understanding ohm’s law is critical to understanding how electric circuits work. Understanding why it is not an actual physical law is critical to understanding the basic principles of logic and the nature of physical laws. Suppose […]
