Step 4: Use the Capacitor to Light the LED Watch the LED…
““Step 4: Use the Capacitor to Light the LED Watch the LED while removing the battery. The LED shouldn’t turn off right away when you disconnect the battery. Instead, it should stay lit for a second or so and then fade out slowly until there’s no more energy left in the capacitor.””
About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
The capacitor stores charge, allowing the LED to stay lit briefly after the battery is removed, demonstrating energy retention and discharge.
In simple terms: A capacitor lets an LED glow briefly after power is cut.
Key Takeaway
Observe capacitor behavior before removing power.

Questions to Reflect On
- What does the LED’s fade‑out tell you about the capacitor’s capacity?
- How could you measure the discharge time more precisely?
A Different Perspective
If the LED does not stay lit, the capacitor may be faulty or incorrectly connected.
