    Urgent question but simple problem

    is it because the maximum limit of 90 degress phase difference is exceeded? another example: V = 2sin(wt+10) i = sin(wt+210) voltage leads current by 200 degrees?

    Urgent question but simple problem

    Urgent question but simple problem:Phase difference Homework Statement What is the phase relationship between voltage and current? i = 5sin(wt+30) V = 10sin(wt+140) Homework Equations The Attempt at a Solution it seems that drawing using cartesian, the voltage is leading the...

    Improper integral help: coloumb's law

    yeah typo: (\frac{z}{\sqrt{p^2 + z^2}})_{-\infty}^{\infty} the problem is differentiating \sqrt{p^2 + z^2} when i keep using LHR it keeps on going back edit: wait did you mean this? \frac{\frac{z}{z}}{\frac{\frac{\sqrt{p^2+z^2}}{z^2}}}} i tihink i get it now just divide both sides by z the...
