A line graph showing peak current in amperes on the vertical axis versus angular frequency in units of ten thousand radians per second on the horizontal axis. The curve rises sharply to a peak near 3.5 on the horizontal axis, marked with a dotted line labeled omega sub r, then falls symmetrically. The background is light blue.
