Why Americans don’t use electric kettles stove top?

‘ If you’re wondering why Americans don’t often have kettles in their homes as Brits do, it’s because they have a lower voltage in the States. While in the UK, our homes operate on 220 and 240 volts, in the States, they have 100 volts meaning electric kettles heat up slower.

What is the kettle effect?

The Half-Time Kettle Effect (HTKE) is an oft-reported part of the football season. The idea is very simple: at half-time, a large number of people watching the match will make themselves a cup of tea, using an electric kettle to do so. The HTKE is the resulting “spike” in the demand for electricity that this causes.
