Electric cookers are among the most common and the most used household appliances in the world. They are simply cooking equipment that makes use of electricity by converting it to heat energy, which is utilised for cooking meals.
Usually, electric cookers are consist of four stoves and about two ovens. The cooker has a set of knobs for each stove and the oven to regulate their temperature.
Electric cookers are very similar in appearance and build to gas cookers, but the major difference is that gas cylinders power gas cookers.

Types of electric cookers
The types of electric cookers that are commonly known and used include:
- Hot plates
- Rice cookers
- Slow cookers (Crock Pot)
- Electric kettles
Brief history of electric cookers
The first models of electric cookers were unsatisfactory in U.S.A due to a host of factors such as high cost of electricity, poor temperature regulation, short lifespan of heating elements and limited power supply from the electricity generating company.
With time, the issue of short durability of heating elements was solved with the invention of nichrome alloy for the manufacture of resistance wires.
In the early 19th century up until the 1920s, the electric cookers/stoves were considered a novel kitchenware and penetration into the consumers’ market was difficult.
However, this changed for the better barely a decade later in the 1930s, when the acceptance of this novel kitchenware became higher due to two improvements on the invention. This includes decreased electric power cost and a more modernised look/appearance of the kitchenware.
Electric cookers were also used as an instrumental tool in the fight for increased demand for electric power supply. They were used to demonstrate their cooking function with electric power during the rural electrification projects.
Types of burners/hobs in electric cookers
Ceramics jobs are primarily liked for their effectiveness, affordability and style. Ceramic hobs are effective because it uses its electric heating elements underneath a glassy surface. The heating begins when you set your knob to get the temperature you want for your hob/burner.
The heating elements heat up the glassy surface, which in turn heats your pot and cooks your food.
Ceramic hobs have attractive pros such as being easy to install, possessing a sleek-looking glass surface, which adds to the aesthetic appeal of a modern kitchen. But everything with pros comes with its fair share of cons.
The cons of ceramic hobs are; the glass surface is breakable, and the hobs are not as responsive as gas hobs and induction hobs.
Air venting induction hobs/burners
This type of burner is a hybrid of induction burners and cooker hoods. This burner has an air vent that serves two primary purposes; Ducted extraction, which is the venting of air outside and Recirculation, which is the venting of clean air back into the room.
The pro of this burner is that due to the location of the air vent which is on the burner instead of being above it, it makes removal of grease and moisture while cleaning easier.
Induction hobs are fairly novel, and that’s why they are not commonly seen in household kitchens like ceramic and gas hobs.
Induction hobs have a coil underneath its surface through which electric current passes. This current while running through the coil creates a fluctuating magnetic field which is responsible for heat transfer to the cooking pot placed on the hob’s surface.
Unlike other hobs, the induction hobs possess a unique feature, and that is they don’t heat up until a cooking pot or something else is placed upon its surface.
Induction hobs possess attractive pros such as having an aesthetic appeal, cooks fast, and it is safe to use.
Gas hobs, unlike the other hobs, can fit in any kind of kitchen design or interior. It doesn’t matter whether the kitchen is modern or traditional.
It is a very functional burner because it is quick to produce an evenly spread temperature across the surface of your cooking pot or pan.
The gas hob connects to the gas mains, so when you switch your hob, a spark is generated by an ignition point. This spark lights up the hob.
They are arguably the most popular hobs. They are fast for cooking, precise, and like others, they are pleasing to the eyes as well.
