circuit design

Oct 26, 2007 8 Replies

I need a scematic that may be easy for many of you but I can't figure it out. I need to create a circuit that I put a 100 ohm resistor on and it gives 3 1/2 volts. plus or minus 5%.



Any help is appreciated.



You're going to have to ask a better question.

Resistors don't make voltage, they resist current flow. What voltage are you starting with and how much current do you need?

I can use as many 1.5 volt batteries as I need. As far as current goes, I don't believe there are any specifications.

Ohhh...this is going to be a case of gigo (garbage in garbage out).

Problem: Create a circuit. It gets a 100 ohm resistor.. Magically turns into a 3.5V source.

Maybe look up linear regulators..

It might be better to describe your objective... Also...it's possible that a non-electronics solution might be posted.

Well, it could be a 3.5V supply with very low output impedance, a 35mA supply with very high output impedance or pretty much anything inbetween. Maybe a bit more information is needed...

Have you also sent this solution to his instructor, so that the OP doesn't expect full credit for the assignment?
