9 Electric cooking range

An electric cooking range is normally a combination of four- an oven and a hot plate. An electric range with a
surface heating element is shown. The arrangement and method of the connection of the two elements in a
surface heating element is shown.
In this type of heater, the element is not opened. The Nichrome wire heating element is kept inside a mineral
insulated hollow tube. The method in which two elements are connected to obtain different temperature is shown
in Fig 3. In the ‘high’ position both the elements are con¬nected across the supply. In the medium position the
high wattage element is connected to the supply. In the medium position the high wattage element is connected
to the supply. In the low position both the elements are connected in series

Toasters
Basically, a toaster is made up of a rack to hold the breadslice, and the heating elements located at the sides of
the of the bread. The object is to heat the bread until it istoasted to the desired colour. The longer the bread is
tested, the darker it will become. Therefore, time plays an important role in getting the desired degree of toasting.
