Kirchhoff's junction rule is a reflection of
1 Conservation of momentum
2 Conservation of current density vector
3 Conservation of charges
4 Conservation of energy
Explanation:
Kirchhoff’s junction law reflects the conservation of charges principle.

If the switches \({S_{1}, S_{2}}\) and \({S_{3}}\) in the figure are arranged such that current through the battery is minimum, the voltage across points \({A}\) and \({B}\) is
1 \(1\,V\)
2 \(4\,V\)
3 \(7\,V\)
4 \(3\,V\)
Explanation:
Current through the battery will be minimum when all the three switches are open. The resulting circuit is shown below. Hence \({V_{A B}=(0.5) \times \dfrac{24}{12}=1 {~V}}\)
