Thinking of a circuit to control the AC power to a heating element. I wanted something fairly linear, and analog. I don't have anything against using a programmable controller, I just wanted to think of an analogue solution, seeing as I don't need to learn how to write a program.
My question: Can I turn this difference equation for R below, into a continuous function R(t)? I have no idea if, or how, I can. And I'd like to.
Equation derived from the following manufacturer statement on the thermal response of a thermistor to a fixed temperature:
My question relates to electronics soldering, where the main metal in the solder is Sn, with small amounts of Ag and/or Cu
If a rod of Cu, Ag, or Au is placed in molten Sn, which of the rods would melt away fastest?
Is there a threshold temperature up to which the solid metals won't...
If I have a problem of the form:
A1ek1t + A2ek2t = C
where A1,A2,k1,k2,C are real and known
ex + AeBx = C
I can turn it into an nth degree polynomial by Taylor Series expansion, but I'd like to know what other methods I can study
