A) The equivalent emf \[{{\varepsilon }_{eq}}\] of the two cells is between \[{{\varepsilon }_{1}}\] and \[{{\varepsilon }_{2}}\], i.e., \[{{\varepsilon }_{1}}<{{\varepsilon }_{eq}}<{{\varepsilon }_{2}}\]
B) The equivalent emf \[{{\varepsilon }_{eq}}\] is smaller than \[{{\varepsilon }_{1}}\]
C) The \[{{\varepsilon }_{eq}}\] is given by \[{{\varepsilon }_{eq}}={{\varepsilon }_{1}}+{{\varepsilon }_{2}}\] always
D) \[{{\varepsilon }_{eq}}\] is independent of internal resistances \[{{r}_{1}}\] and \[{{r}_{2}}\]
Correct Answer: A
Solution :
(a) The equivalent emf \[{{\varepsilon }_{eq}}\]of the two cells is between \[{{\varepsilon }_{1}}\] and\[{{\varepsilon }_{2}}\], i.e., \[{{\varepsilon }_{1}}<{{\varepsilon }_{eq}}<{{\varepsilon }_{2}}\].You need to login to perform this action.
