Q: What is the correct answer for CUET UG Physics Q41?

The correct answer is d. The relationship between the terminal potential difference (V) of a cell, its electromotive force (E), the current (I) flowing through it, and its internal resistance (r) is given by the equation V = E - Ir. The student is plotting a graph with V on the y-axis and I on the x-axis. This equation can be compared to the standard form of a straight line, y = mx + c, where 'm' is the slope and 'c' is t

Q41. In an experiment, a student in the laboratory measures the terminal potential difference (V) of a cell (emf E and internal resistance r) as a function of current I flowing through it and plot a graph taking V on y-axis and I on x-axis. What is the slope of the graph between V and I?

The relationship between the terminal potential difference (V) of a cell, its electromotive force (E), the current (I) flowing through it, and its internal resistance (r) is given by the equation V = E - Ir. The student is plotting a graph with V on the y-axis and I on the x-axis. This equation can be compared to the standard form of a straight line, y = mx + c, where 'm' is the slope and 'c' is the y-intercept. In our case, y = V, x = I, the y-intercept c = E (the EMF of the cell when no current is drawn), and the slope m = -r. Therefore, the slope of the graph between V and I is -r.
