What characterizes the secondary winding in the ignition coil?

• A. Few turns of soft wire
• B. Many turns of fine wire
• C. Few turns of thick wire
• D. Many turns of coarse wire

Answer: (B)

The secondary winding in an ignition coil is characterized by having many turns of fine wire. This design is crucial because it helps achieve the high voltage necessary to create a spark at the spark plug. The extensive number of turns allows for the induction of a higher voltage when the magnetic field collapses, which is a key function of how ignition coils operate. Using fine wire is also important as it allows for more turns to fit within the limited space of the coil. The thin wire has a higher resistance compared to thicker wire, which is essential in this context because it aids in boosting the voltage. Overall, the configuration of the secondary winding is specifically tailored to maximize the voltage generated for efficient ignition of the air-fuel mixture in the engine.
