A: The coil is really a transformer. The 12 enter the coils and charges with current as the point opens up this charge is released as energy about 100 mw. This release is transformed to hi voltage at the secondary by a primary to secondary turn ratio like 1:3333 more or less. Since the primary is open the same ratio will feed the primary that is why we see ringing and the point have capacitor to protect from false firing.

The coil is a transformer, but we know that DC will not work with a transformer. A supply of 12 volts DC is applied to the coil's primary winding. In series with this coil is a set of breaker points. These points are used to interrupt the 12 volt supply from the coil. When the 12 volt supply is interrupted, the magnetic field around the primary winding collapses. This collapsing field induces a voltage into the secondary coil of the transformer. The secondary coil has many more turns that the primary coil and the voltage induced will be in the 10,000 to 15,000 volt range. This high voltage is needed to make the voltage jump across the air gap in the spark plug.

Why induction type instrument canot be used for dc measurements?
Induction is a property of voltage changes, which does not occur with Direct Current devices. There are exceptions, such as the coil of an automobile, which charges up to a high voltage between ignition discharges, but the voltage supplying the coil does not vary.
What is the function of a coil?
An ignition coil (also called a spark coil) is an induction coil in a automobile's ignition system which transforms a storage battery's 12 volts to the thousands of volts needed to spark the spark plugs.This specific form of the autotransformer, together with the contact breaker, converts low voltage from a battery into the high voltage required by spark plugs in an internal combustion.source is from http://www.madabout-kitcars.com/kitcar/kb.php?aid=269
Can you use an ignition coil as primary transformer of Tesla coil?
yes,ignition coil can also be used to energise the Tesla coil very well ,because it is also a type of high voltage potential transformer and it can be used in manner of fly back configuration used this and I'm satisfied that it works same as other H.V t/f just there is need of little modification required to energise it and its output also i.e square wave to sinewave...
Why is primary coil in step up transformer thick?
A step up transformer converts low voltage,high amperage current to a high voltage,low amperage current. It requires large diameter wire to carry the high amperage in the primary coil.
Can tesla coils generate an emp?
the coil it is used to produce high voltage, low current, high frequency alternating current electricity. A burst of electromagnetic radiation is something the coil will not do.
What does the condenser do on a distributor?
The condenser serves to enhance the spark by greatly increasing the voltage to the input of the ignition coil. It does this through a sudden electrical surge and a high frequency ringing effect, bringing the voltage as high as 300 volts for input to the coil immediately after the ignition points break.
What does a condenser do on distributor?
The condenser serves to enhance the spark by greatly increasing the voltage to the input of the ignition coil. It does this through a sudden electrical surge and a high frequency ringing effect, bringing the voltage as high as 300 volts for input to the coil immediately after the ignition points break.
Where source and what parts of high voltage in ignition system of car?
The coil generates the high voltage charge which is then distributed to the spark plugs by the rotor arm in the distributor cap.
What does a coil do in a motor vehicle?
The spark plug requires a very high voltage for the spark to leap the gap between the contacts and provide a source of ignition. The coil does this by changing the voltage from the battery/alternator from a very low voltage to a very high one through a process called induction.
Where is the coil on a riding lawnmower?
Most mowers don't have a coil, they use magnetos for ignition. If it does have on it steps up voltage to a high level to jump the spark plug gap.

What is an ignition coil on a 14.5 Briggs and stratton lawnmower motor?
It is the same as an ignition coil on all internal combustion engines. It is a high voltage transformer that provides a spark at just the right time to ignite the air-fuel mixture in the combustion chamber.
What is the function of a car Distributor?
The distributor send high voltage from the ignition coil to the spark plugs. It ensures that they fire at the correct time and in the correct order.
How did Nikola make the Tesla Coil?
He took an alternating current generator, and used that as it's base. Then, used a spark gap and an HAWG capacitor for the secondary energy source. He then used a transformer and an ignition coil to serve as the bases power transmitor.
What is the correct name for the coil or high tension voltage capacitor that Leads to a Spark Plug?
The correct name for the coil that leads to the spark plug is an ignition coil. If you go to a parts store and ask for anything else they will not know what you are talking about.
What are the four basic part of ignation system?
The four basic parts of an ignition system are the ignition coil, distributor, spark plugs, and the battery. The ignition coil generates high voltage to ignite the air/fuel mixture in the combustion chamber. The distributor distributes the high voltage to the correct spark plug at the right time. Spark plugs then produce the spark to ignite the air/fuel mixture in each cylinder. The battery provides the electrical power to the ignition system.
What does a coil on a gas lawnmower do?
it converts a low voltage to a high voltage.
