Homework Help: Current/displacement current in oscillating emf problem

  1. Dec 6, 2009 #1
    1. The problem statement, all variables and given/known data

    An oscillating emf drives a series combination with circular plates with emf of (170V)sin[400 rad/sec)t], resistance of 0.9 megaohms, radius of 42 cm, and a separation of 1.9mm. Find the rms current in the resistor. Find the rms value of the displacement current between the capacitor plates.

    2. Relevant equations
    v= IR
    displacement current = d (electric flux)/dt x epsilon naught

    3. The attempt at a solution
    14.2 amps for rms current in resistor, but I think I'm way off, someone please help!
