DOD and THD
THD Electronics was created in 1986.
What is the THD
hotplate
To heat most liquids.

A hotplate is a small and portable kitchen appliance that features a heating element that can be gas-powered or electric. They are generally used for food preparation.
Yes, an induction hotplate is safe to use if you are careful. Make sure to use oven mitts when handling anything that is hot.
If your hotplate is not heating your solution or whatever you are trying to heat enough, I suggest some modifications to your container. You could try insulating say the glass flask with glass wool. There are also special insulating materials that are used for this purpose. If you do not have a separate temperature control for the hotplate you can try that too.

An electric kettle is generally more efficient than an electric hotplate for boiling water. This is because electric kettles are specifically designed to quickly and efficiently heat water using less energy compared to a hotplate, which is a more versatile but slower option for heating water.
It is Total Harmonic Distortion, and has to do with how "clean" the output power is. For those of us in the lighting and electrical world, THD refers to the Harmonic Distortion present with most electrical equipment, and more specifically now, the distortion present with electronic ballasts. THD is the measurement of the distortion created from the equipment's current draw. True resistive loads, such as an incandescent light bulb, do not have THD. Equipment containing coils and capacitors, such as motors, drives, fluorescent lighting and HID lighting, have some measure of THD.
