Quiz: Do you Know how Induction Cooktops Work?
What do you know about induction cooking? Is induction cooking better than conventional cooking? Take our thought-inducing quiz to learn about induction cooking.
How does an induction cooktop compare to conventional cooktops?
- heats faster and is easier to clean
- easier to clean but cooks at a lower temperature
- heats more slowly but reaches a higher temperature
What is heated during conventional cooking?
- the food only, not the cookware
- the entire surface of the pot or cookware
- the surface of the pot or cookware that touches the heat source
How precisely can temperature be controlled through induction cooking?
- very accurate
- not at all accurate
- depends on the brand
The term electromagnetism refers to the relationship between __________.
- protons and electrons
- electricity and magnetism
- magnetism and electrons
How does electromagnetism occur?
- A circuit of alternating current causes a current to flow in another circuit.
- A direct current such as a battery causes a current to flow in another circuit.
- A magnetic field generates electricity and sparks an alternating current.
What scientific principles are bound by Faraday's Law?
- All electric currents have gravitational forces that generate magnetic fields.
- All electric currents have magnetic fields, but alternating currents have magnetic fields that fluctuate and induce other currents to flow.
- All electric currents have induction properties, but magnetic fields generate more currents to flow.
How does induction cooking work?
- Coils carrying alternating current affect the surrounding magnetic field and induce current in the cookware.
- Electromagnetic current heats the cookware by causing the coils beneath to reach high temperatures.
- Ferromagnetic cookware generates an electric current in the cooktop and heats the food.
How many volts are induced in the cookware surface during induction?
What are eddy currents?
- swirling currents
- small electric currents
- incomplete circuits
Why is iron the material of choice for induction cookware?
- It is an excellent conductor.
- It converts the flow of the current into heat.
- It allows currents to flow easily through it while generating high heat.
Are aluminum pots a good choice for induction cooking?
- only if they have copper bottoms
- only if they have iron bottoms
How can you tell if your pot is suitable for induction cooking?
- If a magnet sticks to the bottom of the pot, it'll probably be good for induction.
- If your pot is ovenproof, it'll probably be good for induction.
- The bottom of the pot will say "Induction Certified."
How much faster than a conventional cooktop does an induction cooktop heat up?
- 10 to 20 percent faster
- 25 to 50 percent faster
- 50 to 75 percent faster
How much radiation does induction cooking emit?
- less than an airport scanner
- more than an airport scanner
- about the same as a small x-ray
What is the price comparison between induction cooktops and gas ones?
- Induction cooktops can be three times the price of gas ones.
- They cost around the same.
- Gas cooktops are more expensive.
Why might the installation of an induction cooktop be unsuitable above an oven?
- It would sit too low.
- It would be inaccessible by people in wheelchairs.
- It might have a fan underneath.
How much heat radiates from an induction cooktop surface?
- minimal heat
- the same as a conventional stovetop
What were induction cooktops originally designed for?
- nuclear testing
- restaurants and industrial use
- chemistry labs
What voltage and amperage do you need for induction cooking?
- 110 to 120 volts and more than 50 amperes
- 208 to 240 volts and up to 50 amperes
- 208 to 240 volts and up to 100 amperes
What features do most induction cooktop appliances have?
- safety lock, pan size adapter and warmer
- safety lock, overflow detecter and auto shut-off
- safety lock, turbo mode and auto shut-off
