material, eg copper, has lower resistance than steel length - longer wires have greater resistance thickness - smaller diameter wires have greater resistance temperature - heating a wire increases ...

Plot a graph of resistance, R, in Ω on the y-axis against length, l, in cm on the x-axis). Draw the line of best fit. We can see from the graph that as the length of the wire, l, increases ...

Traditionally, condensed matter physics is split into "hard" condensed matter physics ... Current research projects include very basic topics (what is the resistance mechanism in thin-film ...

Superfluidity is a quantum mechanical effect that occurs at temperatures near absolute zero. As the temperatures of certain ...

What is quantum physics? Put simply ... some materials are superconductors that allow current without electrical resistance, and why we can’t get this trick to work at room temperature.

T his pineapple experiment shows the heat-resistance of pineapple skin. This super heated, iron ball was heated to 1800 degrees and then placed on top of the pineapple skin without making a mere ...
