I’d second that. A cheap hair-dryer on ‘LOW’ provides an excellent example of a beefy half-wave rectified load. I’ve attached a picture of what mine looks like. The Green trace is as measured by a current clamp, and the Pink trace is as measured by a CT (note where the zero-point for the Pink trace is via the ‘4’ GND signal off to the left). The CT is trying to keep the signal balanced around 0 and it’s the CT that produces that slow positive ramp during the Green flat-line intervals.
