Question
For a given temperature difference, which of the following pairs will generate maximum thermo e.m.f.
- Antimony-bismuth
- Silver-gold
- Iron-copper
- Lead-nickel
The correct answer is: Antimony-bismuth
As a rule, more the metals are separated from each other in the thermoelectric series, the greater will be the thermo emf.
