A thermocouple, when heated:
A) produces a small dc voltage.
B) produces a small ac voltage.
C) increases its resistance value.
D) decreases its resistance value.
Thermocouple
A type of sensor used to measure temperature, consisting of two different conductors that produce a voltage in response to a temperature change.
DC Voltage
Direct current voltage, where the flow of electric charge is in one direction.
AC Voltage
Alternating Current voltage, where the flow of electric charge periodically reverses direction, commonly used in power supply systems worldwide.

Final Answer :
A
Explanation :
A thermocouple produces a small direct current (dc) voltage when heated due to the Seebeck effect, which is the emergence of a voltage between two different conductors when a temperature difference exists between them.
