Series-path definition — a “series circuit” between two nodes provides only one continuous path for current flow between those points. Assess this definition.

Introduction / Context:
Series and parallel are topological relationships that dictate how voltage and current distribute in circuits. Correctly identifying a series path is crucial before applying Ohm’s law, voltage division, and Kirchhoff’s laws. Misclassification leads to wrong calculations of currents, voltages, and power ratings.

Given Data / Assumptions:

• The statement defines a series circuit as a single current path between two nodes.
• Components are ideal and connections are perfect conductors.
• Steady-state analysis is considered for simplicity.

Concept / Approach:
In a strictly series connection, every electron that leaves the source must pass through each element sequentially and return—there is no branching node that creates alternative paths. Consequently, the same current flows through all series elements, while voltages across them generally differ according to their individual impedances (V_i = I * R_i for resistors).

Step-by-Step Solution:

Verification / Alternative check:
Use Kirchhoff’s Current Law at each intermediate node; with one path only, the current in equals the current out and equals the same I everywhere. Measurements with an ammeter in multiple series locations will read the same current (within instrument tolerance).

Why Other Options Are Wrong:

Common Pitfalls:
Assuming components are in series just because they are drawn in a line—node labeling must confirm a single path; ignoring hidden branches like measurement shunts or protection paths.

Final Answer:
Correct
