JEE Main 2025 (22 Jan Shift 1)
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.

Correct answer
BStatement-I is false but Statement-II is true
Step-by-step explanation
In parallel connections
$\begin{aligned}
& \frac{1}{r_{\mathrm{eq}}}=\frac{1}{r_1}+\frac{1}{r_2} \\
& \frac{E_{\mathrm{eq}}}{r_{\mathrm{eq}}}=\frac{E_1}{r_1}+\frac{E_2}{r_2}
\end{aligned}$
If and
Statement 1 is false.
is less then both and
Statement II is true
