Current Electricity 2 Question 11
11. 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 $11.5 V$
Show Answer
Solution:
Voltage across load $=I R=\frac{37}{32} \quad(10)=11.56 V$
