what happens to the terminal voltage across the Daniell cell as the current through it increases?
From a voltage-current graph, what is the unit of the slope? what physical quantity does the slope represent? How will one know if the slope of the voltage-current curve is positive or negative?
From a voltage-current graph, what is the unit of the y-intercept? What physical quantity does the y-intercept represent?
