Need help with this please

Answer 1

Answer:

$-3.06$ 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 $= -2.92$

The voltage drop at Tin $= -0.14$

The net voltage

$= -2.92 -0.14 \\= -3.06$
