Final answer:
Technician A and Technician B may both be correct depending on the specific design and requirements of the gun-type oil burner system they are referring to.
Step-by-step explanation:
The question relates to the operation of ignition transformers used in gun-type oil burners, with conflicting information about input and output voltages provided by two technicians. To answer this properly, one must be familiar with the standard voltages used in such equipment, which can vary. However, common input voltages for ignition transformers in residential settings are often around 120 volts, with output voltages that can be around 10,000 volts to generate a strong enough spark. It's also possible for industrial settings to use higher input voltages like 208 volts, especially in configurations connected to three-phase power supplies. The actual specifications can depend on the design and requirements of the specific oil burner system.
