What voltage does a spark igniter operate at?

  1. 1,000 VAC

  2. 10,000 VAC and higher

  3. 120 VAC

  4. 250 VAC

The correct answer is: 10,000 VAC and higher

A spark igniter operates at a high voltage in order to create a spark that ignites the gas in a gas heating system. Typically, spark igniters operate at voltages of 10,000 VAC and higher to generate a strong spark that can ignite the gas efficiently. Lower voltages like 1,000 VAC, 120 VAC, or 250 VAC would not be sufficient to create a reliable spark for ignition in a gas heating system.
