Why is high voltage needed to establish a spark across the gap of a spark plug
The type of hazard whereby sparks are generated electrically is called:
Explosion
contact
fires
strain.
The following statement is made about an ignition system: tech a says that the greater the speed of the magnets rotating past a the ignition coil, the greater the voltage will be induced into the ignition coil. Tech b says that the primary windings produce a higher voltage than the secondary winding. Who is correct?
