A student measures the terminal potential difference (V) of a cell (of emf \(\varepsilon\) and internal resistance r) as a function of the current (l) flowing through it. The slope, and intercept, of the graph between V and l, then, respectively, equal:
- -r and \(\varepsilon\)
- r and - \(\varepsilon\)
- - \(\varepsilon\) and r
- \(\varepsilon\) and -r
Answer
(A) -r and
