why does the light go on when I flip a switch?

The electric company generates (makes) electricty, which they send through wires. These wires go to every house. In some places, you can seem them on the street, but in most places they are underground.\n\nWhen you flip a switch, your are connecting the lightbulb to one of these wires. So electricity flows from the wire to the lightbulb. When you close the switch, you disconnect the 2 wires.\n\nThat is what happens. How electricty is made, and how lightbulbs and switches works is a bit more complicated, but for that I suggest Wikipedia:\n\nhttp://en.wikipedia.org/wiki/Electricity\n\nThe basic idea behind generating electricity though, is that you are freeing electrons from atoms, which then go to other atom/s that absorb them.

There could be several reasons. Too much line voltage, or surges in line voltage, that can occur during lightning storms or when power is restored after an outage, will severely shorten the life of any incandescent lamp.\n\nYou can purchase a "button," to put between the base of the lamp and the socket it screws into, that will increase lamp life by half-wave rectifying the line voltage... essentially discarding half the available power. The penalty is much reduced light output. You can also purchase bulbs with higher rated voltage, for example 130 instead of 120 volts, that will also last longer at lower line voltages (110 - 115 volts).\n\nAnother bulb killer is shock and vibration. It seems like I have to change my porch lights every other week or so because the closing (slamming) of the doors literally shakes them to death. I've tried using so-called "rough service" bulbs and garage door opener bulbs but nothing seems to work well.\n\nThis seems to go along well with someone else's answer that turning the lamp on and off reduces its life. There is a huge thermal shock when a light bulb first lights. Although they are designed with doubly-coiled filaments, delicately supported on wires inside the bulb, the failure mode is always this: the filament breaks.\n\nLess often, but especially for bulbs that burn undisturbed and continuously, the tungsten filament eventually sublimes until it is too thin to support its own weight. This can take considerably longer than the typical 1000 hour life stated on the carton. But one day you turn the light off then back on again and... POOF! it's gone.\n\nIf you can afford the initial cost and don't mind the totally unnatural spectral distribution of the light, compact fluorescent lamps are a better bargain than most incandescent lamps. And soon, white-light emitting diodes (LEDs) will be available with life times of 50,000 hours or more.

There are 2 orange buttons on the front between the speakers. Push the one on the right. The light will turn on now.

When electricity is given, the bulb glows because of the power dissipated from the tungsten. This is because of the heat produced when current flows through the filament. So when the current is switched off, no current flows through the filament causing the heat not to be created. So the bulb stops glowing and light energy is not given out.\n\nSince no electric energy is given, no light energy is given out. The already produced light energy (before shutting off) i.e. the photons, are absorbed by surrounding objects so that it no longer produces light.\n\nThe photons are the smallest unit of light like cells in biology. Photons have energy in them. These energies are absorbed by surroundings.

I can't stand it when people leave a room without turning the lights off. I usually dash back inside the room after the person leaves, to correct the problem. I'm not like that with most things but...

there should be a botton (like a light switch) that you can push to see if your light shuts off! but your prolly jus asking this ? to be a smart ass!  \n\n*sometimes when im board i like to put my little brother in there to make sure it shut off!

You turn it off and turn it back on...

b/c a constant amt. of electricity is going into it, and it will only get brighter if you add more electricity to it, or get a brighter bulb!

vice versa (pronounced vice-uh vers-uh) means "with position turned" and is used when two things go the same way.\n\n"When I flip the switch up, the light comes on and vice versa [when I flip the switch the other way, the light goes off]."

You can wake us up from the dead for that reason, and all that you will get from most guys is undying gratitude. For many men, that switch is rarely in the "off" position, and if it is, not much effort is required to get it to the "on" position. Your man is a lucky one, and I hope that he appreciates you.

You aren't clear about whether the switch is on in both measurements.  If it is, then the voltage will be the same.  If not, then the voltage will be different because of the voltage drop across the internal resistance of the battery.

If it's plugged in, or the batteries are charged, I usually push the "ON" button.

HMM.  Maybe if you turn on switch A and leave it for about 2-3 minutes. Then turn it off.\nThen turn on switch b and head upstairs.\nThe light controlled by switch b will still be on.\n\nThe light controlled by switch A will be off but still warm to the touch.\n\nThe light controlled by switch C will be cold.\n\nThink that will do it?

Infinite when the switch is open.\n\nLittle or zero when the switch is closed.

This is a nice problem.\n\nSwitch on one of the bulbs and wait for it to heat up. Turn in off and switch another one. Go downstairs, and feel the hotness. The hot bulb corresponds to the first switch and the one that is on the second switch. The one that is off is for the switch that has not been touched.

Unplug it for a good 5 minutes so it can reset itself to the factory settings.\n\nOtherwise, it sounds like a safety feature.  Perhaps a fuse is out, or a connection has cracked.  No manual, huh?

It means there was a power surge in the system and the main fuse box either in your house or at the main power station flipped to the off postion...also known as being tripped. Normally a safety device or circuit breaker will 'trip' when it is detecting too much load...eg a faulty appliance, too much appliances plugged in (use of too many adaptors), or hot electrical joint (loose), undersized protection etc.
