Homework Help: Electricity in a R-L circuit

  1. Dec 5, 2004 #1
    Electricity in a R-L circuit!!!

    How do I show that R/L has units of time? Do I take the deriviative or what?

    Go by the basic definitions of resistance and inductance and "break them down into the fundamental units".

    Well, I think the point of the problem is to use the ratio and plug in some of the circuit equations. I'm not sure if this is for a grade or what, so I won't explicity say which equations. Just remember that for R and L in series, only one current goes through them. You have expressions for current in terms of R and L...plug and chug.
