Led Torch
Why an LED flashlight has a duration of more than a collection of cells that an incandescent lamp?
Eh! To Please answer the question correctly, it is my duty to physics professor gave us any notes or explain something. Why an LED flashlight has a duration of more whole cells of a filament lamp? And also: The bulb must have an operating voltage C. ___ What is the voltage? My teacher is really a doctor. And he likes biology, and do not know as well as physical. So I guess that's why. Do not write not the issue, was in a worksheet that has given us. With a diagram of a torch, and we had to label 2 questions. diagram also includes 3 cells. If it helps ... (:
There is no "might" respect. It is a guessing game, not a matter of opinion. LED consumes less energy. This is the only answer. If your professor actually read the question and the teacher is not qualified to teach physics. Regarding the second question, no answer is possible because there are an infinite number of possible answers. You have provided data sufficient for a significant response.
