Mr Studiot I am a competent engineer and I have employed other engineers for over 30 years. The product in discussion is a UL approved product (very safe). I don't expect any free engineering although I have provided same to many struggling engineering students over the years. I am exploring...

I was trying a back bias pass through with the two diodes in series but it sounds like current caring capacity is not there. The reason I would like a two wire solution is for ease of assembly and installation. These products are assembled by my customer and they like the simplicity of a non...

The length of the wire is not an option for this application. I have looked into thyristors and that could be a good solution. I am interested in a fixed voltage lower than 60VRMS with a 120VAC input. Do they make a two wire version that has a fixed voltage pass? I am also looking at schottky &...

I have a company that makes electrical resistance heaters. We have an application where we are trying to achieve 60 or less watts in a 5' 120VAC heater. The problem we have is that the heating element wires need to be on the order of 24ohms/ft and that ends up being a small gauge wire (ie 40 ga...

Thanks folks! I wil be puting all this to a test here in the next couple of weeks. I am testing a new Thermal program called win-therm. I may be able to combine that program with a modifacation to a solid scape type program that will electrically then thermally simulate objects with both...

Thanks for your response. I am new to this form, but have all ready managed to meet the police first off. We can use the diameter of the center connection point, call it .025". The application is one of heating. I have a piece of graphite I have purchased in an effort to design a disk shaped...

Resistance=resisivity(of a certain material)Xlength/cross-sectional area resisivity is expressed in ohm-cm I have a graphite material that is 6ohm-cm the material is .032" thick I will cut the graphite material into a 3' disk I will place an electrode in the center of the disk and have...
