Homework Statement



Design an RC circuit that has the same Voltage vs. Time characteristics as the RL circuit shown

*See attached Diagram*

Homework Equations





The Attempt at a Solution



Not really sure how to approach this, but all i know is the equations:

RC circuit:

Vc(t)=Vb(1-e^-(t/RC))

RL circuit:
i(t)=(Vb/R)(1-e^-(tR/L))

I really don't know how I'm supposed to use the equation for RL... am I using ohm's law? I am really confused so any help would be great!

hi dancergirlie! :smile:
*See attached Diagram*
where? :cry:
RC circuit:

Vc(t)=Vb(1-e^-(t/RC))

RL circuit:
i(t)=(Vb/R)(1-e^-(tR/L))
now write an equation for V(t) for RL, and get that to look like the V for RC :smile:
