4. An AC source of amplitude Vo and angular frequency w, V=V simwt, is connected across a ic SLC parallel plate capacitor C1, (a) Verify that the displacement current in the capacitor is the same as the conduction current in the wires. (b) Determine the magnetic field intensity at a distance, r from the wire. 1 Given a vector field F=xyaz-2xa, find its circulation around the path OABO shown in the figure. 1 [hint: equation of a quarter circle x +y2 =9.(x20, y53)]. 4.
