Solution

The correct option is D 6V
Assuming copper slab to be ideal conductor i.e R $=$ 0
$\Rightarrow E = I r$
$E = 12 \times 0.5$
$E = 6 V$

The internal resistance of an accumulator battery of emf 6 V is 10 $Ω$ when it is fully discharged. As the battery gets charged up, its internal resistance decreases to 1 $Ω$ . The battery in its completely discharged state is connected to a charger which maintains a constant potential difference of 9 V. Find the current through the battery (a) just after the connections are made and (b) after a long time when it is completely charged.
