Current Electricity Ques 30
- Two batteries with emf $12 $ $V$ and $13 $ $V$ are connected in parallel across a load resistor of $10 $ $\Omega$. The internal resistances of the two batteries are $1 $ $\Omega$ and $2 $ $\Omega$, respectively. The voltage across the load lies between
(a) $11.7 $ $V$ and $11.8 $ $V$
(b) $11.6 $ $V$ and $11.7 $ $V$
(c) $11.5 $ $V$ and $11.6 $ $V$
(d) $11.4 $ $V$ and $11.5 $ $V$

Answer:
Correct Answer: 30.(c)
Solution:
Formula:
Voltage across load $=I R=(\frac{37}{32}) \times (10)=11.56 $ $V$
