WebScientists create a galvanic cell in which one half-cell contains the half-reaction to be determined. The other half-cell is a standard hydrogen electrode (SHE) in which the half-reaction is: 2H⁺ + 2e⁻ = H₂ E° for the SHE is defined as 0.00 V. Then E° for the half-reaction is the same as the measured value of E° for the cell. WebSolution. The emf value ( ε) of the battery, the current (I) flowing through the battery, and the load resistance (R) are all given in the question. This is the right equation to use to find the internal resistance (r): ε = I · R + I · r. Let ’ s put the given variables into the equation:
