An ignition transformer increases voltage from 120 to _______ volts. An electronic ignitor spark generator supplies a 14,000 volt spark to ignite the oil.

An ignition transformer increases voltage from 120 to _______ volts. An electronic ignitor spark generator supplies a 14,000 volt spark to ignite the oil.

• A. 10,000
• B. 5,000
• C. 14,000
• D. 24,000

Answer: (A)

Ignition transformers in oil burners are used to take the standard 120-volt line and step it up to a high voltage large enough to create a spark across the burner electrodes. The typical secondary voltage for these transformers is about 10,000 volts, which is sufficient to ionize the oil mist and bridge the gap to ignite. The electronic ignitor can produce a spark around 14,000 volts, which helps ensure ignition, but the transformer's normal rating being around 10,000 volts is what the question is asking. So, the missing voltage is 10,000 volts.
