Which outcome lowers efficiency when dissimilar metals form a thermoelectric cycle?

💡 Explanation

Joule heating dominates reduces thermoelectric efficiency because current passage generates heat irreversibly, rather than cooling. Therefore, less energy converts usefully, rather than increasing power output with greater heat differential owing to other thermoelectric effects.
