The cooker uses electrical power to generate heat. It takes a large amount of electrical power to generate a large amount of heat. Since power is current draw times operating voltage, you need a low resistance to draw a large current since you can't increase the operating voltage.
Mathematically speaking, Ohm's Law (E=IR) gives the relationship between voltage (E), current (I) and resistance (R). Since power (P=EI) is what is produced and is related to the heat produced, rearranging the elements gives a second equation that relates power to voltage and resistance (P=E2/R). So you can see that for a constant voltage (E), a low R value gives a high power (P) value.

How many amps for a 13.8 kw cooker?
The formula you are looking for is Amps = kW x 1000/1.73 x Volts x pf. The pf (power factor) of resistance heating will be 1. If the cooker was rated in kVA the same formula would be used minus the pf.
Which electric heater will yield the greater heat output a large resistance in the coil or a small resistance in the coil?
A small resistance in the coil will yield greater heat output in an electric heater. This is because a small resistance allows for a larger current to flow through the coil, which in turn generates more heat due to the increased power dissipation (P = I^2 * R).
When is the current flowing in a circuit said to be very small?
The current flowing in a circuit is said to be very small when it is in the range of microamperes (10^-6 A) or even lower. This low current can be indicative of high resistance or very low power consumption in the circuit.
What traps heat in the solar cooker?
Heat is trapped in a solar cooker due to the greenhouse effect. The glass or plastic cover of the cooker allows sunlight to enter, but traps the heat energy inside, increasing the temperature inside the cooker and cooking the food.
What is the difference between a Bunsen burner and a gas cooker hob?
A Bunsen burner is a device used for heating in laboratories, with a vertical gas nozzle and adjustable air inlet for controlling the flame. A gas cooker hob is a kitchen appliance for cooking food, with multiple burners for heating pots and pans. The main difference is in their design and intended use, with the Bunsen burner being more specialized for scientific purposes.
Is a 10 cup rice cooker large enough for a small family?
A ten cup rice cooker would cook at least twice the amount of rice a small family would need. A three cup cooker is sufficient for most small families. A ten cup cooker would be more appropriate for a large family or if you expected to have friends over for a gathering.
What is the energy transfer in an electric cooker?
In an electric cooker, electrical energy is transferred into heat energy through resistance in the heating element. The electrical current passing through the element encounters resistance, which generates heat as a byproduct. This heat energy is then used for cooking food.

Where is resistance used in everyday life?
In a cooker. Unless you're using a 'halogen' cooker - the heating elements on the hob and within the oven and grill are simply large resistors, that heat up when power is applied.
Best Small Pressure Cooker?

How to thicken sauce in a slow cooker?
To thicken sauce in a slow cooker, you can mix a small amount of cornstarch or flour with water and stir it into the sauce. Let it cook for a bit longer to thicken.

How can Whirlpool microwave ovens support metal accessories -looks like alu?
If the accessories were designed by the manufacturer of the microwave cooker there will be no problems, no matter what they are made of. Its metal objects that the cooker was not designed for that are problems, especially foil or wire as they are high resistance and can cause fires.
When measuring a large current flow should you use a shunt with zero resistance?
It is not a shunt with zero resistance. It is very small, but it is not zero. The large current develops a small voltage across the small resistance. Measuring that small voltage gives you a proportional measurement of the current.
How can I effectively use a pressure cooker for sterilization purposes?
To effectively use a pressure cooker for sterilization, follow these steps: Place the items to be sterilized in the pressure cooker with a small amount of water. Close the lid securely and set the pressure cooker to the recommended pressure and time for sterilization. Allow the pressure cooker to reach the desired pressure and maintain it for the specified time. After sterilization is complete, carefully release the pressure according to the cooker's instructions before opening the lid. Remove the sterilized items and allow them to cool before use.
