What type of load is designed to produce heat by opposing the flow of electric current?
A resistive load is designed to produce heat by opposing the flow of electric current. This type of load converts electrical energy into heat energy through the resistance it offers to the current passing through it. Examples include heating elements in appliances like toasters and electric stoves.
Who found heating effect of electric current?
The heating effect of electric current was discovered by James Prescott Joule in the mid-19th century. Joule's experiments showed that the temperature of a conductor increases when an electric current passes through it.
Practical application of heating effects of electric current?
Disadvantages of the heating effect of electric currents are: short circuits, house fires, and explosions. Advantages of the heating effect of electric currents are: electric light, toasting food, and keeping a room warm.
Why is the filament inside a wire coiled?
The coiled filament in a wire increases the resistance, which in turn increases the amount of heat produced when an electric current passes through it. This enables the wire to function as a heating element in appliances like toasters and ovens.
What does electric current do?
Electric current is the flow of electric charge through a conductor. It produces various effects such as heating, lighting, and magnetism. In electronics, current is used to power devices and transmit signals.
Heating Effect of Electric Current advantage?
Reliable, simple and safe. Heat can be regulated by changing the resistance in the circuit.

Do toasters have a motor?
No. Toasters generally have heating elements, a mechanical or electronic timer, and a spring loaded tray on which toastable items rest. There are some larger industrial model toasters that do have electric motors that pass toastable items past the heating element, typically on a chain belt, but the toaster in your kitchen is not likely one of these.

What is used in heating toasters?
Electricity

Which type of substance would you use as a heating coil in an electric toasters?
I believe I would select NiChrome wire. It has a high resistance for a metal and is not particularly toxic or expensive.
What purpose of heating element?
A heating element is used to generate heat in devices like ovens, toasters, and electric stoves. It converts electrical energy into heat through resistance, allowing these devices to cook or heat food.
Why does the cord of an electric heater not glow while the heating element does?
The heating element of an electric heater is a "resistor", the cord which conducts the electricity is not. The resistance of the element of an electric heater is very high. As current flows through the heating element, it becomes red hot and glows. On the other hand, the resistance of the cord is low. It does not become red hot when current flows through it.
What wire is used for an immersion heater?
An immersion electric heater usually uses nichrome wire as the heating element. Nichrome is highly resistive, and by applying a voltage, we can get it pretty hot. Nichrome is used as the heating element in toasters and on electric range elements as well as lots of other places.
What effects of electric current is involved in the fuse breaking?
Heating Effect.
