What else can I help you with?
Can we clean nichrome wire with sulphuric acid?
No, it is not recommended to clean nichrome wire with sulfuric acid as it can cause corrosion and damage to the wire. It is safer to use a mild solvent or a cleaning agent specifically designed for cleaning metal surfaces.
What happens to a nichrome wire when a current flows through it?
When a current flows through a nichrome wire, the wire heats up due to resistance. This increase in temperature causes the wire to glow and emit heat, which is why nichrome wire is often used in heating elements and appliances.
What has more resistance a nichrome wire or a copper wire?
A nichrome wire has more resistance than a copper wire. This is because nichrome is made of a nickel-chromium alloy that has higher resistivity compared to copper, which allows it to impede the flow of electricity more effectively.
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
Why is it important to use a clean nichrome wire for each flame test?
The wire simply holds the sample in the flame. Nichrome wire has such a high melting point that the relatively low temperature of the burning flame won't drive any of the Ni or Cr atoms into the ionic state and interfere with the color of the ions in the compound which is adhering to the wire.

How is toast made?
Toasters use Nichrome Wire that is wrapped around a Mica Sheet. Nichrome Wire produces infared radiation. This produces the heat that "toasts" the bread. You can usually see this yourself! When the coils inside the toaster start to become red, that means the Nichrome wire is starting to produce infared Radiation.A timer is set to stop the Nichrome Wire from producing heat, and a spring-loaded tray pops the toast out of its slot.

A nichrome wire has more resistance than a copper wire. This is because nichrome is made of a nickel-chromium alloy that has higher resistivity compared to copper, which allows it to impede the flow of electricity more effectively.
What element is used in electroplating and nichrome wire?
The element commonly used in electroplating is nickel. Nichrome wire is made of a nickel-chromium alloy.
What type of substance would you use as a heating coil in an electric toaster?
Nichrome wire. An alloy of Nickel and Chromium.

Does copper conduct electricity better than nichrome?
yes it does -------------------- You might say they are polar-opposites. Copper is specifically used where low resistance is desired. NiChrome is often used as a resistance wire. For example, model rocket engines utilize nichrome wire to ignite the fuel because the resistant wire will glow red-hot when electric power is applied.
Why tungsten metal wire is not used in heater?
A heater does not get hot enough to benefit from the expense of using tungsten wire. Most heaters use either wire made of an alloy called nichrome or plated ceramic heating elements. Heaters generally operate at red or orange heat (i.e. 1409F to 1908F) and can use nichrome wire. Lightbulbs operate at white heat (i.e. greater than 2309F) and use tungsten wire, but tungsten is hard and expensive to make into wire compared to softer metals.
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.
Why is it important to use a clean nichrome wire for each flame test?
The wire simply holds the sample in the flame. Nichrome wire has such a high melting point that the relatively low temperature of the burning flame won't drive any of the Ni or Cr atoms into the ionic state and interfere with the color of the ions in the compound which is adhering to the wire.
Difference between copper wire and nichrome wire?
Copper wire is a good conductor of electricity and is commonly used in electrical applications due to its low resistance. Nichrome wire, on the other hand, is a nickel-chromium alloy with high resistance to heat and corrosion, making it suitable for applications like heating elements in appliances and industrial processes. Nichrome wire is used when resistance to high temperatures is required, while copper wire is used for its conductivity.
