What voltage does the step-up transformer boost from 120 V to in an electric ignition system?

• A. 5,000 - 6,000 volts
• B. 7,000 - 8,000 volts
• C. 10,000 - 12,000 volts
• D. 15,000 - 20,000 volts

Answer: (C)

In an electric ignition system, a step-up transformer is used to increase the voltage from a standard level, typically around 120 volts, to a much higher voltage that is necessary for igniting fuel in internal combustion engines. The correct answer, which indicates a voltage range of 10,000 to 12,000 volts, is accurate based on the operational requirements of ignition systems. These high voltage levels are essential for creating a strong enough spark to ignite the air-fuel mixture within the engine cylinders. The transformation from a lower voltage to this higher range is critical for effective engine performance and ignition reliability. Understanding this process is important because it highlights the role of transformers in electrical systems, particularly in applications where high voltages are necessary for functionality.
