5F20.50 • Circuit Analysis: Series and Parallel Light Bulbs

Instructions / Notes:

• Use the three-way switch to alternate between the series circuit and the parallel circuit.
• The two directions are labeled for your convenience.
  

---

Concepts Conveyed:

• Demonstrates the difference in bulb brightness between both circuits.
• The parallel circuit should be brighter and the series dimmer.

---

Demo Staff Notes:

• Use the two blocks to prop up both panels at a slight angle.
• Ensure that both circuits work properly.
• If the staff requests, provide additional bulbs with different resistances.
