the metal casing of the electric kettle
Megger the body and the earth point. It should be zero
It's very effective and efficient. It of course uses the earth's heat for heating a building. Only a small amount of electricity is needed for this, compared to the large amount needed for an electric furnace or baseboard heater. Geothermal is very expensive to install, but will make up for the cost in the savings you will have over a period of several years.
Double-insulated electrical appliances, such as electric drills, only require two connections -a line and a neutral- to the supply. An earth (ground) connection is unnecessary. In the UK, all electric socket outlets have shutters that blank off the line and neutral terminals when there is no plug inserted. These shutters are operated by the earth pin of the plug. As double-insulated appliances don't require an earth connection, a plastic earth pin is moulded into the plug in order to open the socket shutters in place of a normal metallic earth pin.
The live wire is brown in coulor while the earth wireis green and yellow in color and neutral wire is blue in colour. Uses of these three wire: Live wire:It's connected with fuse.It carries a voltage which drives electric current through the electrical appliances. Earth wire:It is a safety device and protect us from electric shock. Neutral wire:It offers a return path by electric current.

D. Alignment of the Universe does not contribute to the changing of seasons. The changing of seasons is primarily influenced by the tilt of the Earth's axis as it orbits the Sun (B), along with the varying distance between the Earth and the Sun (C) throughout the year. The distance between the Earth and the Moon (A) mainly affects tides on Earth.
In terms of physical measurement, the distance between Earth and heaven is not known as heaven is considered a spiritual or metaphysical realm, not a physical location in space. Different belief systems and cultures have their own interpretations of where or what heaven is.
The gravitational force between the Earth and sun certainly depends on the distance between the Earth and sun. But the gravitational force between, for example, the Earth and me does not.
The average distance between Earth and the Moon is about 384,400 kilometers.
