Assertion (A) Explained
In nodal analysis, the basic assumption is that we assign a reference node (usually ground) and measure all other node potentials relative to this reference. However, the statement in A suggests that the node potential is always higher than other voltages, which is misleading.
- The node potentials can be higher, lower, or equal to other voltages in the circuit.
- The important aspect is that the potential at any node is defined relative to the reference node, not necessarily higher than all other potentials.
Reason (R) Explained
Nodal analysis is indeed a technique used to determine branch currents, but it does not directly relate to the assumption made in A.
- Nodal analysis focuses on writing KCL (Kirchhoff's Current Law) equations at each node.
- The outcome of these equations allows us to calculate the currents flowing through each branch of the network.
Conclusion
Thus, while both statements A and R are true in their own contexts, R does not provide a correct explanation for A.
- A is misleading regarding the nature of node potentials.
- R correctly describes the purpose of nodal analysis without explaining the assertion.
Therefore, the correct answer is option 'B': both A and R are true, but R is not the correct explanation of A.
