Statement I Two non-ideal batteries are connected in parallel, the equivalent emf is smaller than either of the two emfs. |
Statement II Two non-ideal batteries are connected in parallel, the equivalent internal resistance is smaller than either of the two internal resistances. |
A) Statement I is true, Statement II is also true and Statement II is the correct explanation of Statement I.
B) Statement I is true, Statement II is also true and Statement It is not the correct explanation of Statement I.
C) Statement I is true, Statement II is false.
D) Statement I is false, Statement II is true.
Correct Answer: D
Solution :
Cells in parallel, \[{{E}_{eq}}=\,\frac{\frac{{{\varepsilon }_{1}}}{{{r}_{1}}}+\frac{{{\varepsilon }_{2}}}{{{r}_{2}}}+...+\frac{{{\varepsilon }_{n}}}{{{r}_{n}}}}{\frac{1}{{{r}_{1}}}+\frac{1}{{{r}_{2}}}+...+\frac{1}{{{r}_{n}}}}\] (use proper sign before the Emfs) and \[\frac{1}{{{r}_{eq}}}=\frac{1}{{{r}_{1}}}+\frac{1}{{{r}_{2}}}+...+\frac{1}{{{r}_{n}}}\]You need to login to perform this action.
