What do you call a circuit that has only one path?
The simplest circuit is a single loop of components connected in series; that is, the components are connected head to tail, with the first and last components connected to close the loop and complete the circuit. See the nearby link for the most rudimentary series circuit imaginable.
How does a light bulb turn on and off?
First, to explain the on/off switch:There is an electrical wire connected to the switch. When the switch is in the [ON] position, it is called a closed circuit, when electricity can run through to power the light bulb. When the switch is in the [OFF] position, the switch stops touching the wires, and it is called an open circuit, where the circuit is broken and the electricity cannot flow.Second, light bulbs:Normal incandescent light bulbs are powered when an electric current runs through their filament. Incandescent bulbs' filaments are very thin, and when electricity runs through them they become so hot they glow bright yellow to white.How come the filaments don't burn up? That was a problem Thomas Edison came across when he tried to make incandescent light bulbs; the filaments burned up. He solved that problem by making a vacuum inside the bulb - No air means no Oxygen, and no Oxygen means no burning. (vacuum means absolutely no gas or air inside an area.) However, he had to make very thick walls for that style of bulb. Today, we fill incandescent bulbs with non-reactive gas at the same pressure as outside air, so bulb walls can be nearly paper-thin.Please rate this answer! :D
Describe how a series circuit is put together?
A series circuit has more than one resistor and gets its name from only having one path for the charges to move along. Charges must move in "series" first going to one resistor then the next. If one of the items in the circuit is broken then no charge will move through the circuit because there is only one path. There is no alternative route. Old style electric holiday lights were often wired in series. If one bulb burned out, the whole string of lights went off.
Did Thomas Edison invent the first lightbulb?
Thomas Edison did not invent the first light bulb. He did however improve on existing light bulbs by creating the first useable incandescent bulb.
Three resistors having a value of 10 omes each are connected in series to a 300 volts power source what is the total resistance of this circit?
Three resistors having a value of 10 ohms each, when connected in series, have a total effective value of 30 ohms, even if they're wrapped in tissue, stuffed into a box, and stored in the back of your sock drawer. What, if anything, they're connected to makes no difference. If you take the series string of three resistors out of the box and connect it to the terminals of a 300-volts power source, then the string will conduct a current of 10 Amperes. Each resistor will dissipate 1,000 watts and heat rapidly, until the first one either melts or explodes, whereupon the series circuit will open and the flow of current will cease.
Why won't your brake lights work on 1993 Toyota Camry?
First check the bulbs. If they are good then the switch that is connected to the brake pedal could have gone bad. Hope this helps.
If two bulbs of wattage 25 at 220 volts are connected in series with the supply of 440 volt which bulb will fuse?
either one could. it depends witch one you unscrew first.
The Highbeams on a 2006 Subaru Impreaza will not engage when switch is flipped?
possible multifunction switch, check your headlight bulbs first
When you turn the headlights to full the lights cut out. Where do you start?
you probably would first start out with replacing the headlight bulbs then work to the dimmer switch and electrical system from there you probably would first start out with replacing the headlight bulbs then work to the dimmer switch and electrical system from there
Why wont high beams work high beams work?
First check the bulbs, if the bulbs are good I would suspect the high/low beam switch is bad.
Do I have to connect only ONE end of a string of 32 lights to a 300 Watt 12V transformer or can I connect TWO separate shorter strings of 16 lights to the transformer?
First of all you have to find out the voltage of the light bulbs and how they are connected to make the string of 32 lights in total. PARALLEL CONNECTIONIt is possible that the light bulbs run on 12 Volts each and are connected in parallel to one another across the 12 Volts output of the transformer. Each bulb may be rated at about 9 Watts. (300 Watts / 32 = 9.375 Watts power per bulb.) If that really is what the bulbs are, and they are connected in parallel as described above, you can separate the single string of 32 bulbs connected in parallel into two separate strings, each having 16 bulbs connected in parallel. SERIES CONNECTIONThe other - less likely - possibility is that the bulbs run on only 0.375 Volts each and that they are all connected in series across the 12 Volts output of the transformer. (32 x 0.375 Volts= 12 Volts.)If that is the case then you can split the single string into two physically separate strings but you must still connect the two strings electrically so that all 32 bulbs remain wired in series across the 12 Volts output of the transformer. If you don't do this right, and you connect each of the serially-connected string of 16 bulbs directly across the transformer, two things will happen:i) the transformer will be seriously overloaded and could catch on fire because the current taken by each string of 16 series-connected bulbs will now be 50 Amps instead of 25 Amps. That makes a total of 100 Amps taken from the transformer instead of the original 25 Amps when all 32 bulbs were connected in one string. andii) all the lamps will glow very brightly for a short time until one of them burns out, at which point all the bulbs in the string will go out because they are connected in series. (The first one to burn out will break the series circuit.) As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Bright lights on a 1988 Chevy pickup don't work. Why?
Check the bulbs first, then the dimmer switch and wiring.

First check the fuse, then check the bulbs, then check the switch.
Your low beams on both of your headlights are suddenly not working on your 2003 Chevy Venture Why?
Possibly the multifunction switch (switch in columm). Check the bulbs, fuses etc first

First check the fuse, then the bulbs, then the flasher relay, then the signal switch.
Your brake lights work when you brake not when you turn lights on?
AnswerThe bulbs for the brake lights are usually separate from the normal tail light bulbs. Check and replace the brake bulbs first, and if they are still not working examine the fuses, switch and wiring.
Why does the third brake light work but the side brake lights don't in a 2000 Chevy cavalier?
Check the bulbs first. I had the same problem on a 94 Oldsmobile and it was the dimmer switch. Replaced that and fixed the problem Check the bulbs first. I had the same problem on a 94 Oldsmobile and it was the dimmer switch. Replaced that and fixed the problem
