🔍 Key Concepts

• Typical forward current rating for standard indicator LEDs • Difference between microamps (µA), milliamps (mA), and amps (A) • Effect of exceeding the rated current on an LED

💭 Think About

• Which of these current values is closest to what you’ve seen used for small indicator LEDs on panels or circuit boards? • If 1 amp is 1,000 mA, think about whether a tiny LED could safely handle that much current without burning out. • Compare 1 microamp, 20 mA, and 500 mA: which is in the range usually associated with visible brightness for small LEDs?

✅ Before You Answer

• Verify the typical continuous current rating for a standard 3–5 mm indicator LED (not high‑power types). • Check how many milliamps are in 1 amp and 500 milliamps to see if these seem realistic for a small LED. • Confirm which option is in the tens of milliamps range, which is the normal operating region for many basic LEDs.
