| If it is desired to determine the average temperature across a large duct, what thermocouple wiring technique can be used to generate an emf proportional to the average temperature? |
| A) Multiple thermocouples can be used if they are wired series-aiding, where the sum of the individual voltages is divided by the number of thermocouples. |
| B) Multiple thermocouples can be used if they are wired in parallel, where the sum of the individual voltages is divided by the number of thermocouples. |
| C) Multiple thermocouples can be used if they are wired series-opposing, where the sum of the individual voltages is divided by the number of thermocouples. |
| D) Only one thermocouple can be used, and the hot junction must be strategically located to get an effective average temperature. |
