Measuring the Efficiency of an Electric Kettle

It's easier to get over-unity with a water heater than an air heater. Some off-the-shelf kettles may be over-unity from the factory. In this video, I measure the efficiency of my 1.6L Hamilton Beach kettle, which turns out to be 89%. I do not have a watt meter, such as a kill-a-watt meter, so I used a volt meter and an amp clamp.
