DC circuitsQuestion 629 of 1506

What is the defining characteristic of a series circuit?

  1. All components are connected across the same two points.
  2. Electrons have a single path to follow.
  3. The voltage is the same across every component.
  4. The current splits equally among all the components.
Show answer

Correct answer: Electrons have a single path to follow.

Components in series are in a single chain, so the same current flows through each of them.
