Re: Victors Non-linear!!!

%$#& forum kicked me off mid post! (no offence Brandon!)

Cool stuff!

Very good work Caleb I learned alot! However, Al's simplification does not make a whole lot of sense to me...

It started when I wanted to solve for VOLTAGE not CURRENT to compare Jame's work and the expected model. So, if you examine the simplified equation,

I(t)= (V*(1-e^(-(t*R)/L)))/R

and use the multiplication rule we can take out V and R

I(t)= (1-e^(-(t*R)/L))*(V/R)

If V = IR then V/R = I

Soo... now

I(t)= (1-e^(-(t*R)/L))*I

and the I s cancel? Something is screwy....

Some interesting links while I'm at it!
inductors

Inductors

Step functions

PS, Al is it ok if we ignore the 0.004 ohms resistance in the FETs?
