Question:

Given: an ideal current source is connected in series with an ideal inductor?

an ideal current source is connected in series with an ideal inductor of 50 milliHenriesthe current source is not constant but a time varying sinusoid. the following formula describes the current in the units of Amperes : i(t) 10cos(500t)derive a formula for the voltage across the inductor, in the units of Volts, as a function of time.note that the units of Amperes per second time Henries yields Volts.I KNOW THIS IS A ODE PROBLEM, Im nor sure how to work the problem any help is welcome, thanks in advance.

Answer:

You use the definition of inductance (L) V L*di/dt where V is the induced voltage, and di/dt is the rate of change of current in the inductor. i(t) 10 cos(500*t) di/dt -500*10*sin(500*t) V -25*sin(500*t) note that the current function is not a sinusoid but is a cos function.
