To determine the direction of thermoelectric current in the given scenarios, we will use the thermoelectric series and the principles governing hot and cold junctions. ### Step-by-Step Solution: 1. **Understanding Thermoelectric Series**: - The thermoelectric series ranks metals based on their thermoelectric properties. The order indicates which metal will donate electrons (the one higher in the series) and which will accept them (the one lower in the series). 2. **Cold Junction of Copper-Bismuth**: ...
