A10-mh inductor has a parasitic series resistance of rs = 0.5 ω, as shown below. if the current is given by i(t) = 0.1 sin(20t) a, find vr(t) , vl(l), and v(t).

Then the total voltage is ...

The magnitude of the resultant voltage is √(.02²+.05²); the angle is arctan(.02/.05).

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

two? xd
