📚 Concept Review Weekend review time — let's revisit a core idea in I. Reliability Fundamentals. A batch of LED drivers has a mean time between failures \(MTBF\) of 50,000 hours under continuous operation. Assuming a constant failure rate \(exponential distribution\), what is the approximate failure rate \(lambda\)? 1️⃣ 50,000 failures per hour 2️⃣ 5 x 10^-4 failures per hour 3️⃣ 2 x 10^-5 failures per hour 4️⃣ 2 x 10^5 failures per hour 👀 Think about it before you scroll for the answer... ✅ Correct answer: 3) 2 x 10^-5 failures per hour Correct: lambda = 1/MTBF = 1/50,000 = 0.00002 = 2 x 10^-5 failures per hour. 💡 Exam tip: If an option sounds like textbook trivia rather than something you'd apply on the job, it's usually a distractor.
