A simple description of electric resistance, how the electricity is affected and how the resistance determines the heat output of electric heating elements
This interactive animation describes about the electrical resistance, factors affecting resistance of wire. It also describes about the length of the wire, thickness of the wire, material of the wire and the temperature of the wire. This is a product of Mexus Education Pvt.

Here, I'll introduce how resistance is an electrical friction, in that it takes useful energy and converts it to heat. Resistivity is related to conductance and conductivity, too. See how judgmental I can be?
In this video we start looking at resistance, which we're going to explore in later videos. We look at what causes resistance and how to calculate it. Don't panic if maths is not your subject, I've included a triangle to help you.
We have explained here what is resistance and what is the basic theory behind it.
Useful for CBSE, ICSE, NCERT & International Students Grade : 10 Subject :Physics Lesson :Electricity, Heating and chemical effect of current Topic: Electrical Resistance Resistance is an electrical quantity that measures how the device or material reduces the electric current flow through it. Theresistance is measured in units of ohms (Ω). If we make an analogy to water flow in pipes, the resistance is bigger when the pipe is thinner, so the water flow is decreased.

Georg Simon Ohm (16 March 1789 -- 6 July 1854) was a German physicist and mathematician. As a high school teacher, Ohm began his research with the new electrochemical cell, invented by Italian scientist Alessandro Volta. Using equipment of his own creation, Ohm found that there is a direct proportionality between the potential difference (voltage) applied across a conductor and the resultant electric current. This relationship is known as Ohm's law.
So, electric current works like a river... kinda... Instead of flowing based on elevation, electric current works a little differently. But it's a good metaphor. In this episode of Crash Course Physics, Shini talks to us about electric current, voltaic cells, and how we get electric charge.

This one exposes the myth that more resistance to current flow creates more heat in the electric heating element. This video is part of the heating and cooling series of training videos made to accompany my websites: www.graycoolingman.com and www.grayfurnaceman.com to pass on what I have learned in many years of service and repair. If you have suggestions or comments they are welcome. If you are a homeowner looking to repair your own appliance, understand that the voltages can be lethal, the fuels are highly flammable and high pressures are used. Know your limits.
In the first fraction of a second electrons flowing through a material (i.e. electricity), they move unimpeded. By "holes" in a resisting material almost immediately begin to resist the flow. Researchers have captured the onset of electrical resistance. In this animation of their computational work, the electrons (blue) and atomic nuclei missing an electron -- also called "holes" (because electrons "drop" into them -- (red) show how electrical flow (green) is impeded.

There's a saying that "it's not the volts that kills you, it's the amps" and while that's true in a way, you can't have amps without volts and skin resistance plays a big part too. This video explores all this, introducing voltage, current and resistance for those new to these things.

What comes to mind when you think of electricity? Current, voltage and resistance. What affects the resistance? What makes a conductor be what it is and for that matter, how is it different from an insulator? What happens when the kinetic energy of electrons is gone? Learn about electricity and resistance in a very interesting way through this module. Electricity can be defined as the movement of charged electrons or the charged protons, dynamically as a current. The charged electrons create charge, which are bind together to do work. The electric bulb, fan and other electronic equipment’s work by binding the electrons. Electricity is measured in units of power called as Watts and it is denoted by the letter W. Current can be defined as the rate at which the charge is flowing. An elec...
