Which circuit characteristic describes a series circuit?

Series circuits have a single path for current. The components are connected end-to-end so the same current flows through each one; electrons have nowhere else to go, so the current can’t split. If any part of the loop opens, the entire circuit is interrupted and current stops everywhere. The total resistance in a series circuit is the sum of the individual resistances, and the current is given by I = V / R_total. This single-path behavior is what makes that description the correct one. The other statements describe parallel paths, zero resistance, or the need for parallel branches, which do not define a series circuit.
