Journal Jolts and Physics Phun

Journal 12: A few Christmas's ago, while stringing up the christmas lights around the house and on the tree, when turning them on, the lights all around the tree burnt out.  What I realized now, is that one of the filaments must have burnt out, due to the faulty wiring or that there was an overflow of voltage which the bulb could not handle.  As depicted in the equation: I=delta q/ delta t, the high voltage from the socket may be the reason for the high charge moving across the filament and wire in the short amount of time, thus burning the filament and blackening the bulb's interior, to us the glass part.  In addition the drift speed moving across it may have been too much for the bulb to handle.  Since light-bulbs act as resistors, and as shown in the equation, delta V=I x R(resistance), the amount of current running through, with not enough resistance on the bulb's part could relate to a high voltage difference, thus overcoming the resistivity of the filament that it burnt out.  Similarly viewing the equation R= (resistivity of material)(length of component)/(cross-sectional area), if either one of these components, such as a too thin or too short wire, the voltage flowing across it may have likewise burt out the filament.  That's all don't play with electricity, except in physics.
