    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?

  • Electrical Resistance - Georg Ohm

    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.

  • A Light Bulb Mystery- Electric Resistance // Homemade Science with Bruce Yeany

    A 110 volt light bulb and a 1.5 volt mini light bulb are wired in series to a nine volt battery. What will happen when the electricity flows? This is a nice simple demonstration of how temperature can affect the resistance in a conductor. The result is called a positive temperature coefficient. In metal conductors, there are already a large number of free electrons flowing through it, the vibrations of the atoms cause many collisions between the free electrons and the captive electrons. Each collision uses up some energy from the free electron and is the basic cause of resistance. The more the atoms bump around in the material, the more collisions there are and the friction causes the material to heat up, this then increases the resistance causing the decrease in current flow.
