Question

the component the ignition system uses to convert low - voltage and high current into high - voltage and low current is called the:

a. ballast resistor.
b. advance mechanism
c. condenser
d. induction coil

Explanation:

• Ballast resistor: It limits current, not for voltage - current conversion.
• Advance mechanism: Adjusts ignition timing, not related to voltage - current conversion.
• Condenser: Stores electrical energy, not for voltage - current conversion.
• Induction coil (ignition coil): Uses electromagnetic induction to convert low - voltage, high - current from the battery to high - voltage, low - current for spark plug.

Answer:

d. Induction coil
