Homework Statement
The voltage across the inductor is given by v(t)=L(di(t)/dt).
Determine:
(1.) Tthe voltage v(t)
(2.) The power p(t)=v(t)*i(t).
(3.) The maximum power transferred ( t = ? (in seconds) when power is at maximum).
if the inductance is L=2 and the current i(t) is given by:
(a.) i(t)=13e-200t A.
(b.) i(t)=20cos(2π60t) A.
It's the formula/steps to get pmax that I am stuck on.
Thank you so much!
Homework Equations
See above.
The Attempt at a Solution
I got as far as answering the (1.) and (2.) for each (a.) and (b.), but I do not know how to calculate the pmax.
(a1.) v(t) = -5.2 e-200t V.
(a2.) p(t) = -67.6 e-400t W.
(a3.) ? ( t = ? when power is at maximum).
(b1.) v(t) = -4.8 π sin(120πt) V.
(b2.) p(t) = -48sin(240πt) W.
(b3.) ? ( t = ? when power is at maximum).
Thank you very much!
