Q. No.Two batteries with emf \(12~\text{V}\) and \(13~\text{V}\) 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:
1. \(11.6~\text{V}~\text{and}~11.7~\text{V}\)
2. \(11.5~\text{V}~\text{and}~11.6~\text{V}\)
3. \(11.4~\text{V}~\text{and}~11.5~\text{V}\)
4. \(11.7~\text{V}~\text{and}~11.8~\text{V}\)
