  1. I am interested to learn at such an elderly age ( being an interesting subject) Thank you. Teach me more!

    1. Of course! It’s wonderful to hear about your interest in learning, regardless of age. Learning is a lifelong journey, and it’s never too late to explore new subjects and expand your horizons. Feel free to ask any questions you have or let me know which subject you’d like to delve into, and I’ll be more than happy to provide you with more information and guidance.

  2. I building a small electrical project for fun, a miniature wind turbine.
    The small turbine is 3v-12v DC and the batteries I want them to charge are two 6v batteries.
    I’m pretty sure I need a diode between the turbine and the batteries, but not sure what size or
    should I say strength diode is needed since the wind never blows at a consistent speed.
    Can you offer any advice on how to figure this out?
    Thanks in advance,

    1. You’re on the right track thinking about using a diode between the turbine and the batteries to prevent reverse current flow. For instance, if your wind turbine generates a maximum of 1 amp at 12 volts, you’d want a diode rated for at least 1 amp and with a voltage drop less than 0.7 volts. A 1N4001 diode, for example, could work.

      Remember that wind speed variations may cause fluctuations in the turbine’s output, so it’s a good idea to have some margin when choosing your diode’s specifications.

      Good luck with your project, and I hope it powers up those 6v batteries effectively!

  3. Hi im working on a government vehicle 12v’s that needs lighting outfitted. Im working on total of 4 scene lights front/left/right/rear.@ some point all lights will be connected to the same wire for all “ON” then would like to independently have a switch for each light. What type of diode would I need if the lights draw 5amp each?

    1. To achieve independent control of four scene lights on a vehicle while still allowing them to be collectively turned on, you can use diodes and switches. Diodes will prevent backflow of current from one lighting circuit to another. For a 12V system with lights drawing 5 amps each, you’ll want diodes with a current rating of at least 5 amps. Schottky diodes are commonly used for this purpose due to their low voltage drop.
