spark coil การใช้

• For this reason, induction coils were called spark coils.
• The spark distributor was replaced with ECU Controlled Spark Coils.
• The engine was developed from the single-spark coils and NGK longlife spark plugs.
• This later gave way to the famous and more sensitive galena crystal sets . spark coil from Ford Model T automobiles.
• Kokomo Electric Company was established to manufacture spark coils and spark plugs for automobiles, and other ignition and electrical related goods.
• One of the poles of the secondary coil of the spark coils is connected to the spark plugs in an ordinary manner.
• The ignition system was " jump spark coil with vibrator operated by dynamo and storage battery . " The wheelbase was with standard tread and wheels.
• The Freeman transmitter broke down  in a fit of rage, de Forest threw it overboard  and had to be replaced by an ordinary spark coil.
• The entire apparatus was known as the'Model T spark coil'( in contrast to the modern ignition coil which is " only " the actual coil component of the system ).
• When the main relay is activated the battery voltage is reformed to 400 V DC which is stored in a capacitor . 400 V voltage is connected to one of the poles of the primary coil in the four spark coils.
• In a June 23, 1910 notarized letter that was published in a catalog produced by the Electro Importing Company of New York, Herrold reported that, using one of that company's spark coils, he had successfully broadcast " wireless phone concerts to local amateur wireless men ".
• After noticing that the high-voltage spark coils used to excite X-ray tubes were becoming popular as transmitters for radio amateurs, he joined two other employees in 1906 to start the Clapp, Eddy, and Eastham Company ( subsequently Clapp-Eastham ) in Boston, to sell spark coils, variable capacitors, and other radio devices.

• The Model T ( built into the flywheel ) differed from modern implementations by not providing high voltage directly at the output; the maximum voltage produced was about 30 volts, and therefore also had to be run through the spark coil to provide high enough voltage for ignition, as described above, although the coil would not " buzz " continuously in this case, only going through one cycle per spark.
• For example, in December 1916 " QST " magazine, an amateur operator working on long distance message passing describes one way to avoid interference was to send messages " . . . on Thursday nights, when the children and spark coil'hams'are tucked up in bed " ( a spark coil was an unsophisticated radio transmitter, made from an automobile ignition coil, that produced noisy interference ).
