Due to temperature variation along a conductor, potential variation occurs along it. This phenomenon is known as :
aThomson effect✓ Correct
bJoule effect
cSeebeck effect
dPeltier effect
eNone of the above/More than one of the above
Explanation
When the two ends of a conductor are kept at different temperatures and an electric current flows through it, heat is evolved or absorbed along the length of the conductor; this is known as the Thomson effect.
