Complex numbers simple circuit

  1. Sep 22, 2008 #1
    1. The problem statement, all variables and given/known data
    Code (Text):


     |      |
     |             |
    +|         ___ C   
     Vs     _
    -|      |
     |      |            

    Find Is

    3. The attempt at a solution

    Z= R+\frac1{jwC}


    Is=\frac{coswt}{R+\frac1{jwC}} * \frac{(jwC)}{(jwC)}

    Is=\frac{coswt*jwC}{RjwC+1} * \frac{(1-RjwC)}{(1-RjwC)}



    My book is pretty crappy so there are no examples

    Is it right until that point? Can I simplify it some more? what is the best form to put it on? how would it look in exponential form?

    Input appreciated
