Energy - Physics A to Z
... When electricity flows through any material, it naturally encounters resistance. Materials with low resistance (such as copper) are called conductors, whereas materials with high resistance (such as rubber) are called insulators. The resistance extracts energy from electric currents, and converts it ...

... The sums of the forces in the y and r directions are then ΣFy = FN cos θ − Ff r sin θ − W = 0 ΣFr = FN sin θ + Ff r cos θ = mac We would like to solve for the frictional force to get the answer. Comparing the two equations above we can see that both equations have FN as the first term, but one is mu ...

Magnetic Field
... the magnetic field exerts a force on the moving charge carriers which tends to push them to one side of the conductor. A buildup of charge at the sides of the conductor will balance this magnetic influence w/ E-field, producing a measurable voltage between the two sides of the conductor. The charge ...
