What you have is resistive electric stove. It is not the same as an induction stove.

Right, but duty cycling is a common method of output control. I've seen induction cooktops (presumably cheap ones) that also has the same behavior.

Sure all inductions jobs will use duty cycling (pulse width modulation if we’re getting technical). But that doesn’t determine responsiveness.

With a resistive hob (ceramic hob is the industry name) you’re relying on a large lump of stone (hence the name ceramic hob) to be a heat store and even out the elements lumpy power output. Problem with this approach is that it takes forever for the stone to heat up and cool down, so the hob is slow to respond.

With an induction hob, your heating pan directly with a electromagnetic field, the only thermal mass in the entire system is the pan. The hob can instantly change its power output, because its not relying on a stone to store energy, and thus has zero thermal mass.

So induction hob react at the speed of your pan, you have lightweight pan, then the pan temperature will change almost instantly. You got a heavy cast iron pan, then the pan will take a little longer to shed the extra heat.

FYI: If the hob glows when heating, it’s not induction. It’s a ceramic hob. Ceramic hobs are crap and give induction hobs a really bad name because the look the same when off. You can only tell if an induction hob is, if there’s a pan on top. They’re incapable of creating heat without a pan on top.
