perpendicular to each other. This configuration is used in beam-focusing devices as well as in a class of devices called magnetrons (seethe sectionMagnetrons). In this case the motion of the electrons is a combination of translation and circular trajectories. The resultant trajectory is acycloid...
for varying distances from the symbol. If the figure of rotation were quadratic (circular, parabolic), the resultant object would be a lens, which would not produce the substantially constant spot size for varying distances from the symbol. The figure of rotation can be a line, in which case...
which heats conductors. Copper and aluminium can conduct a huge amount of current without damage, but much before conductor damage, the insulation would, most probably, be damaged by the resultant heat.

Too much of a good thing is also bad, it is said. In terms of rising number of gadgets and resultant e-waste around us, the above refrain surely makes a lot of sense. The question that may beg an answer is what is e-waste in the first place? The term e-waste is...
