How do you find the length of a coil of wire without unraveling it?
You know that each 'wrap' or turn of wire in the coil has to go all the way around the coil-form, and you know how to calculate the distance around a circle. So all you have to do is count the number of times the wire goes around the coil, measure the coil's diameter, calculate its circumference, and multiply that by the number of turns in the coil.
What would happen if someone touched a Tesla Coil while it was on?
what would happen if some one touched a Tesla coil while it was on??? it depends on lots of factors ...is the person in good health ....it is humid out are you sweting is the coil hooked up to a 120volt or 220 volt line is it on hi .....Tesla coils make Static Electricity (lighting) and a lower Amprage ....Amps are what kills people not volts volts burn ....but if the volts are high enough the electricity runs on the outside of your body through your skin and swet (well the salt in your swet) and is harmless but if you tauch the coil and a ground (ie) pipe,chimminey,wire,something electronic ...it could be fatal read any instruction that came with your kit coil or your coil package ....if you made your ciol froma set of internet plans BE CAREFULL depending on how good you are at reading and fallowing the instrutions it could be a matter of life and death ....if you tauch the coil with a florecent tube it will light up and there is other things to play with such as a clear light build (any wattage) or a neon build just be carefull till you get a feel for it...and allways have some one there incase something does go wrong....play safe
Why the strength of electromagnetic increases when the current in the coil increases?
Because when energy goes farther it needs more power to go the distance and so there is your answer
How you can make a clamp on ammeter?
Go to radio shack. Ask for "Alligator clips". Buy a few that the tip of your ammeter probe fits snugly into the wire loop. You now have an ammeter probe with a clip on the end. Cost: ~$1 Alternatively, they sell pre-manufactured clip leads for most ammeters, which consist of a plug-in jack to the meter, a wire and an alligator clip at the other end. They're around $20. If you mean a "clamp-on" ammeter that detects current by proximity to a hot wire, I don't know how to make one, other than the fact that they work on the principle of induction coils. Probably a multi-meter and a coil of wire would suffice to *detect* current. You'd have to calibrate readings for your specific coil with known currents to use it for a reading other than hot/not-hot. BUT: At around $30 for a cheapo clamp-on meter, you're undoubtedly better off buying one, or just learning to use a multi-meter and probing the wire. Homemade electronic devices are fun until your DIY project gets you killed trying to prox text 440V 3-phase with your jury-rigged science project...
On a light switch where does the white wire go and where does the black wire go?
(Note: this is US information. Other countries may use other color codes; consult an electrician in your local area.) Standard color coding for single-phase electrical wiring is that the neutral wire is white and the "hot" wire is some other color, usually but not always black. If the switch has instructions or a wiring diagram, follow that. If not, normally the white wire should be connected to the lighter (silver colored) terminals on the switch and the "hot" wire should be connected to the darker (brass colored) terminals. Some switches interrupt both electrical paths, and in those the terminal screws may be the same color and it doesn't matter which wire goes to which set of terminals (just don't cross them). If there are green terminal screws, those are for the green grounding wire.
How do you test a lawn mower ignition coil?
Remove the kill wire from the ignition coil. It's the only wire that doesn't go to a plug. Remove one of the spark plugs. Reconnect the plug wire to the plug that has been removed. Make sure the threads of the plug are touching metal on the engine somewhere. Crank the engine. Should see spark. If not, bad coil.
Can you retrofit an older riding mower to have an emergency shutoff?
yes run wire from ignition coil to bottom of seat use spings or whatever you not to make the wire ground to the seat pan when rider exits the mower this will automatically shut the engine down when rider falls off to save yourself some time and cash just go and find a 2 wire seat switch off of an old riding mower and run one end of wire to coil and the other to common ground
Where is the ignition coil located on a 95 Honda Accord 2.2 4-cylinder?
If you see no center coil wire connector then the coil is mounted inside the distributor. If there is a center coil wire connecter then follow the coil wire and it will go to the coil.
You have no spark on your old snapper lawn mower and you would like to know what all you to look at to gain spark?
Your mower gets it spark from a coil that is under the engine shroud. There is a magnet on the flywheel that with each revolution causes the coil to spark. Possible problems are: 1) There is too much rust on the coil or flywheel to let the current go between the two. Taking them apart and lightly sanding them until you get a clean metal surface usually takes care of this problem. 2) If it is a riding mower, there is a ground wire that shorts out the coils which stops the mower when the key is turned off. If the ignition switch is bad it should cause a no spark issue. Or, the wire could be pinched somewhere and killing the engine. You can remove the spark plug, unplug the small black wire off of the coil and see if it sparks then. If it does then this is your problem. 3) The coil itself could be bad.
How do you make a kill switch for a mower?
Any gasoline engine on lawn & garden equipment is killed by shorting out the coil, also known as the magneto, this is the part the spark plug wire comes from. Killing the engine is merely shorting it out, a ground wire, so you could actually run a toggle switch with a wire to the coil. If this happens to be a Briggs & Stratton they have a spade connection on the side of the coil you can connect to, Tecumseh has a wire ran from within. It is not clear above that you need to connect to the low voltage side of the coil. This will depend on the stype of motor, but you can short or open the points or open the ground for the magneto. Don't connect to the high-voltage wire going to the spark plug or you will be in for a nasty surprise when you go to use it.
Does the wire form the distributor go to the pos termial of the coil?
Assuming you have an older vehicle with points, the wire from the distributor goes to the neg side of the coil.
If no spark is happening does that mean it could be the coil?
I would suspect you are talking about a gasoline engine and if so than yes if the coil is bad you will not get a spark. But that is not the only reason why you may not have spark. Pull the coil wire off and pull the insulation back on the end of the wire, stick a screwdriver into the coil where the wire should go, then hold the wire about an 1/8 away from the metal part of the screwdriver and have someone try to start the engine if the coil is good it should arc between the screwdriver and the wire. Be careful to only hold the insulation on the wire and the nonmetalic handle on the screwdriver, a coil can give off up 100,000 volts, it won't kill you but it hurts like hell.
Where is the kill switch on a lawn mower?
Push mowers have kill switches that are on the handle and kill the engine if you let go and riding mowers sometimes have kill switches under the seat to kill it if the rider gets off the mower.
What is the center wire on 1995 Ford Distributor cap go to?
The coil
Is there a coil wire that goes to the optispark on a 95 Pontiac firebird with a 57L LT1 and where does it go?
The wire goes to the coil, which is bolted to the drivers side head in the front of the motor.

You want to go back to a points dist and standard coil from a mallory how do you do it as to the wiring?
There shouldn't be any difference in the wiring. The hot wire from the switch goes to the + side of the coil, and the pigtail wire from the points goes to the - side of the coil.
