解题步骤

1. Understand the question
   1. what type of circuit is a string of holiday lights in which one light bulb burns out causing the whole circuit to stop working?- closed parallel circuit- open series circuit- closed series circuit- open parallel circuit
2. Brief Explanations

   In a series circuit, all components are connected end-to-end in a single path for current flow. If one component (like a burned-out bulb) fails, it creates an open break in the single path, stopping current entirely and making the whole circuit non-functional. Parallel circuits have separate branches, so one failed component doesn't stop the whole circuit. A closed circuit is complete and working, while an open circuit has a break that stops current.

3. Final answer

   open series circuit
