The Shockley ideal diode equation or the diode law is derived with the assumption that the only processes giving rise to the current in the diode are drift (due to electrical field), diffusion, and thermal recombination–generation (R–G) (this equation is derived by setting n = 1 above). It also assumes that the R–G current in the ... Parametric equations allow the direction or the orientation of the curve to be shown on the graph. Equations that are not functions can be graphed and used in many applications involving motion. See .

Aug 19, 2019 · Method 1. From the graph, the y-intercept appears to be 20. The graph also appears to go through the point (20, 70). Using the procedure described previously, you arrive at the equation y = 5 2 x + 20. To find the x value that returns a y value of 100, substitute 100 for y, and solve: Let's see, the constant of proportionality for equation C, if we wanna solve for y, we could divide both sides by six. And so we're gonna get y is equal to 3/6 times x. Well, 3/6 is the same thing as 1/2 times x, and so there you have it. We have a constant of proportionality of 1/2. That's the choice I like.
