Series Circuit

​A series circuit is an electrical circuit in which every component is connected in a single path. Series circuit consists of a single closed loop. Electricity flows around the series circuit in a single path.

Parallel Circuits:
How would you describe these connections?

Parallel Circuits

A parallel circuit carries electric current along two or more paths.

Watch Video in Edio on page 4.

Multiple Choice

Which of the following statements best describes how the bulb brightness differs between a series circuit and a parallel circuit, each with two lights?

• Bulbs in a parallel circuit are brighter than in a series circuit.
• Bulbs in a series circuit do not light up at all.
• Both circuits have the same brightness for the bulbs.
• Bulbs in a series circuit are brighter than in a parallel circuit.

​Observations:
bulbs remain brighter because each path receives the full voltage

Parallel Circuit with Two Loads and a Switch

​Now, slide the switch back and forth. Observe the lights as you slide the switch. What effect does the switch have on the lights? Record your observations in the table in Electrical Circuits
