Question
Given below are two statements :
Statement-I : The equivalent emf of two nonideal batteries connected in parallel is smaller than either of the two emfs.
Statement-II : The equivalent internal resistance of two nonideal batteries connected in parallel is smaller than the internal resistance of either of the two batteries.
In the light of the above statements, choose the correct answer from the options given below.
Select the correct option:
A
Statement-I is true but Statement-II is false
B
Both Statement-I and Statement-II are false
C
Statement-I is false but Statement-II is true
D
Both Statement-I and Statement-II are true
✓ Correct! Well done.
✗ Incorrect. Try again or view the solution.
Solution
$=\frac{\frac{\varepsilon_1}{\mathrm{r}_1}+\frac{\varepsilon_2}{\mathrm{r}_2}}{\frac{1}{\mathrm{r}_1}+\frac{1}{\mathrm{r}_2}}=\varepsilon$
