Answer:
[tex]-3.06[/tex] is the overall voltage produced
Explanation:
Potassium and Tin are connected in an electrochemical series.
In a series circuit, the resultant voltage is equal to the sum of voltage drops at all points in the circuit.
Here,
The voltage drop at potassium [tex]= -2.92[/tex]
The voltage drop at Tin [tex]= -0.14[/tex]
The net voltage
[tex]= -2.92 -0.14 \\= -3.06[/tex]
