series circuit
Technical term in electronics; a circuit where components are connected end-to-end so current flows through each one in turn. Contrasts with 並列回路 (parallel circuit).

In a series circuit, the current is the same everywhere.
Please explain the difference between a series circuit and a parallel circuit.
並列回路 is a parallel circuit where components are connected side-by-side, providing multiple paths for current. 直列回路 is a series circuit with a single path.
Compound of 直列 (series, in a line) and 回路 (circuit). The exact historical derivation is uncertain; the term is a modern technical coinage.
