Which of the following components low voltage is converted into high voltage for ignition?

The ignition coil is a key component in an automotive ignition system that is responsible for transforming low voltage from the battery into the high voltage necessary to ignite the fuel-air mixture in the engine's cylinders.

When the ignition key is turned on, the battery supplies a low voltage, typically around 12 volts, to the ignition coil. Inside the coil, this low voltage is stepped up to a much higher voltage, usually between 12,000 and 45,000 volts. This high voltage is then sent to the spark plugs, creating a spark that ignites the air-fuel mixture.

Understanding the role of the ignition coil is crucial for diagnosing ignition problems, as it is essential for starting the engine and ensuring proper combustion. In contrast, the battery stores electrical energy, the starter motor is responsible for cranking the engine, and the alternator generates electricity to recharge the battery and power electrical systems while the engine is running. These components are vital to the overall operation of the vehicle, but the specific function of converting low voltage to high voltage for ignition is uniquely performed by the ignition coil.
