🔍 Key Concepts

• Radio Frequency Interference (RFI) generated by ignition systems (spark plugs) • How high‑voltage ignition pulses can be suppressed before they radiate as noise • Which components in the list are actually in the ignition circuit vs. just in the power circuit

💭 Think About

• Which choice directly affects the high‑voltage pulses going to the spark plugs themselves? • Which options deal only with battery or starter wiring and would not change the sharp ignition pulses that occur every time a plug fires? • Think about how adding resistance at the noise source might reduce rapid current changes and therefore radiated interference.

✅ Before You Answer

• Identify which option is physically connected in series with the spark plug leads/ignition system • Eliminate options that only modify battery starting current and not ignition pulses • Confirm that the selected method is commonly used in automotive practice to reduce ignition noise in radios
