Which statement about the Intelligent Ignition System’s voltage handling is supported by the material?

• A. The transformer boosts primary voltage to 300-500 volts.
• B. The capacitor discharges into the coil at 18 volts.
• C. Both statements are correct.
• D. Neither statement is correct.

Answer: (A)

The key idea is how the system handles high voltage to create the spark. In this Intelligent Ignition System, the design uses a transformer to raise the voltage from the primary side to a much higher level—roughly 300 to 500 volts—before delivering or storing energy for ignition. This higher voltage level is what allows enough energy to be stored in the subsequent stage (like a capacitor or the coil) to produce a strong spark. The notion that a capacitor would discharge into the coil at only 18 volts doesn’t fit with how these systems typically operate. Capacitors in ignition circuits are charged to hundreds of volts, not a low 18 volts, and then they dump that energy rapidly into the coil to generate the high-voltage secondary spark. So the statement about boosting to 300–500 volts is the one that matches the described voltage handling, while the other idea reflects a lower-voltage scenario that isn’t consistent with this design.
