# Current/displacement current in oscillating emf problem

#### awakeinroom8

1. Homework Statement

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. Homework Equations
v= IR
displacement current = d (electric flux)/dt x epsilon naught
