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.

What is the difference between a Bunsen burner and a gas cooker hob?
Bunsen burners are quite small though gas cooker hobs are quite big!
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.
Can you place dry ice into a pressure cooker without it exploding?
When the dry ice is placed on the cooker it will explode, unless the temperature of the cooker is at a low degree.
When is the current flowing in a circuit said to be very small?
When the current flowing in a circuit is very small the resistance will be very high.
How much water do you put in a pressure cooker?
The volume of the pressure cooker (unless it exploded).
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.

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.
What is the difference between a Bunsen burner and a gas cooker hob?
Bunsen burners are quite small though gas cooker hobs are quite big!
Best Small Pressure Cooker?
The "best" small pressure cooker can depend on your specific needs and preferences. Some well-regarded options include the Instant Pot Duo Mini, the Presto 01341 4-Quart Stainless Steel Pressure Cooker, and the Hawkins Contura Pressure Cooker. Consider factors like size, features, and budget when choosing the best small pressure cooker for you. It's always a good idea to read customer reviews and product specifications to ensure it meets your requirements. my recommendation:ππ₯π₯π‘π€://π¨π¨π¨.πππππ€π₯π π£πππ.ππ π/π£ππππ£/πππππ π/πΈππππππππ/
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 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.

How calculate unknown resistance?
-- Connect a source of known, small voltage across the ends of the unknown resistance. -- Measure the resulting current through the unknown resistance. -- Divide (small known voltage)/(measured current). The quotient is the formerly unknown resistance.
What is the ability to move a large resistance with a small effort?

Do batteries have resistance?
Yes they do have a resistance. Even though a battery is a voltage source it has some thevenin resistance. Every lead plate and cell of sulfuric acid, will have a small resistance. The thevenin resistance is equivalent or sum of all those resistances.
