First, check whether the circuit works without the capacitor. If not, then go back to Step 1 and get the LED circuit working before you move forward. If the LED lights up with the battery connected but turns off the instant you remove the battery, then something is wrong with the capacitor part of your circuit. Check that the capacitor’s positive leg is connected to the positive battery leg (row 1 in the photo) and that the other leg is connected to the negative battery leg (row 10 in the photo). If the circuit looks correct, confirm that the capacitor value is at least 1000 µF; the value should be written on the capacitor. If it’s less than 1000 µF, try a bigger capacitor.”” [Oyvind Nydal Dahl](https://sms4smile.com/quotes/author/oyvind-nydal-dahl/) ## About This Quote This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation. When a circuit fails, verify basic operation before adding components; ensure correct polarity and sufficient capacitance. **In simple terms:** Check the circuit works without the capacitor and use the right polarity and size. Key Takeaway Test the basic circuit first, then add the capacitor correctly. Themes electronics troubleshooting design Mood practical methodical Type instructional technical When to use this quote - DIY electronics - educational labs - prototype development - repair workshops Key Concepts circuit analysis capacitor polarity component testing Questions to Reflect On - What other components could cause similar symptoms? - How does capacitor quality affect performance? A Different Perspective If the circuit works but the capacitor fails, the issue may be elsewhere, like wiring or battery health. ★ ★ ★ ★ ★ No ratings yet [Capacitor Circuit](https://sms4smile.com/quotes/about/capacitor-circuit-4196932/) [Check Capacitor](https://sms4smile.com/quotes/about/check-capacitor-4196931/) [Circuit Working](https://sms4smile.com/quotes/about/circuit-working-4196934/) [Confirm Capacitor](https://sms4smile.com/quotes/about/confirm-capacitor-4196933/) [Led Circuit](https://sms4smile.com/quotes/about/led-circuit-2434678/) [Move forward](https://sms4smile.com/quotes/about/move-forward/) ## Related quotes > [“Step 1: Start with the LED Circuit Follow the instructions from “Project #9: Your First Breadboard Circuit” on page 84, making sure you end…](https://sms4smile.com/quotes/oyvind-nydal-dahl/step-1-start-with-the-led-circuit-follow-the-instructions-from/) [Oyvind Nydal Dahl](https://sms4smile.com/quotes/author/oyvind-nydal-dahl/) > [I was 17 when I was forced into marriage.
