356897 A student measures the terminal potential difference (\(V\)) of a cell (of emf \(\varepsilon \) and internal resistance \(r\) ) as a function of the current (I) flowing through it. The slope and intercept of the graph between \(V\) and \(I\), respectively, equal to

1 \( - \varepsilon \,{\rm{and}}\,r\)
2 \(r\,{\rm{and}}\, - \varepsilon \)
3 \( - r\,{\rm{and}}\,\varepsilon \)
4 \(\varepsilon \,{\rm{and}}\, - r\)

356899 A cell of emf \(E\) and internal resistance \(r\) is connected in series with an external resistance \(n r\). Then, the ratio of the terminal potential difference to emf is:

1 \(\left(\dfrac{1}{n}\right)\)
2 \(\dfrac{1}{(n+1)}\)
3 \(\dfrac{n}{(n+1)}\)
4 \(\dfrac{(n+1)}{n}\)

356900 Assertion :
Terminal potential difference of cell is always less than its emf.
Reason :
During discharging of a cell the terminal potential difference is less than emf.

1 Both assertion and reason are correct and reason is the correct explanation of assertion.
2 Both assertion and reason are correct but reason is not the correct explanation of assertion.
3 Assertion is correct but reason is incorrect.
4 Assertion is incorrect but reason is correct.
