I appreciate your time here, thank you for the formula. I haven't come across that one yet. I'm using "Foundations of Electronic Circuits and Devices" 4th edition which probably has all of this information but I don't always know what I'm looking for. I'll investigate what you've given me...
okay I understand the voltage drop better. As discharge and recharge occur, Q and C are changing. So how did you get to 36.8%?
I attached our plan. Thank you very much for all your help :)
If this gets out of hand or there is another source for this stuff, please let me know :)
What causes the voltage drop?
Also, I was going to build this on a basic stamp which would provide 5v DC but you think I need something that can put out more amps?
My daughter and I are building a little robotic arm and I want to check my math before we start ordering parts.
We are using a piece of flexinal (.11 ohms resistance per inch & 12 inches long, and requires 4amps per cycle to actuate with a cycle time of approximately 14 seconds) and want to...
