What electric element should be used so as to open the closed electric circuit?

What are electric baseboard heaters classified as?
Heating device or heating element.
Can we verify ohm's law by using filament lamp?
The answer is NO. Ohm's law states that current (I) flowing through the conductor is proportional to the potential difference (V) developed across its ends, keeping physical conditions such as pressure, temperature, strain constant. In a filament lamp, the heating element used is Tungsten (W) which has high melting point and resistivity. Due to which , when current passes through it gets heated up and glows producing light and heat. As more and more, current flows through it, it gets considerably heated, resulting in increase of temperature. This is against the requisite condition "constant temperature". Hence Ohm's law cannot be verified using filament lamp because the temperature varies when the current flows through it.
Can an ac element be run on DC?
DC voltage can be used to run almost any device utilizing an electric heating element, including resistive baseboard and electric water heaters. In these applications, electrical current flowing in a heating element produces heat due to resistance.
19 An electric heating element is connected to a 110 V circuit and a current of 3.2 A is flowing through the element How much energy is used up during a period of 5 hours by the element?
1,760Wh
Which element is used to make the filament of electric bulbs?
They're made of Tungsten.
Which element are used as an electric heater filament?
Nichrome wire is commonly used for resistance wire for heater elements and it is a non-magnetic alloy of two elements nickel and chromium. It has high resistance and resists oxidation. The electrical resistivity is about 65 times that of copper.
Which element is used in element bulbs as filament?
tungsten
What is a filament element?
A filament is the little wire you see inside of a light bulb that glows normally reddish or orangish when you supply electricity to it such as when you turn on the "LIght Switch". I just simplified it alot, if you need to know more in depth just let me know on this qustion page. An element can also exist in appliances as larger, such as the upper and lower elements in an electric oven, on top of the stove like a burner in electric ranges or in electric water heaters.
What is a filament resistor?
A filament bulb resistor is the common type of light bulb. It contain a thin coil wire called filament. It produces light as a result. It is made mainly from the element tungsten. The metle tungsten has very high melting point and it is a good conductor of electric current
What is the difference between a filament of a bulb and an element of an electric heater?
The heater element is thicker wire, and has lower resistance. It still has enough resistance to glow red hot (producing heat) but does not glow white-hot and very brightly like a light bulb filament. Also, it lasts almost indeifnitely. whereas the light bulb filament has a finite life - it will "burn out" sooner or later.
Which element is used in which element is used in light Bulbs as a filament?
Tungsten
Which element is used in a light bulb filament?
Tungsten is an element. It is used in bulbs
Should the heating element of an electric iron be made of of iron Silver or nichrome wire?
It should be made of nichrome wire because resistivity of nichrome is high.Its high resistivity causes nichrome to heat up faster, when an electrical current is passed electricity moves through the wires, givingheat to the element.hope it helped
What is the coil of the wire called in a light?
element Filament
What element is in an incondescent light bulb filament?
Tungsten.
What element is used for a filament for light bulbs?
Tungsten
