What happens to a nichrome wire when someone turns on a switch?
It will get heated and start to glow.
Why is nichrome used for heating element in a toaster?
A nichrome wire has high resistance and gets heated faster, saving electricity.
Why a copper wire in a closed circuit does not get heated?

How was the lunar module heated?
The Apollo lunar module was heated electrically. from batteries and an electric fuel cell.
When a circuit is opened what happens?
Nothing. An open circuit means no current is flowing. When the circuit is closed, current flows, the filament of the bulb is heated by the current and glows, giving off light. But when the circuit is open, nothing happens.
Why is a copper wire in a closed circuit does not get heated but a nichrome does?
this is because copper wire offers no resistance and thus electric current passes through them without producing heat energy whereas in nichrome offers a large resistance and thus the mechanical energy of the drifting electrons changes to heat energy rapidly .

How electric geyser works?
A electric Geyser has a Element screwed in the side of the inner water container, with the heated side submerged in water, parallel to the element (sometimes center) is a thermostat unit to control the temperature by switching the element off once the desired temperature has been reached. The element itself is made with nichrome wire, which is a resistive wire, When a Electric current is passed through the nichrome wire the resistance of the wire restricts the current causing a pressure of electrons and protons (as water builds pressure in a hose pipe when the end is restricted) and intern creates heat as a byproduct.
Why will the current flow be different in a heated rear screen circuit than a side light circuit?
the heated rear screen circuit has a higher resistance compared to the side light circuit
Why do metals do not catch fire when heated whereas paper ignites on heating?

What happens to an electric motor if it is over heated?
If a fuse fails to blow or a cut-off doesn't come into play, the insulation on the wires will melt and cause a short circuit.

Will a nichrome wire light up when heated?
Nichrome is a name for a nickel- chromium resistance wire, a nonmagnetic alloy of nickel and chromium. Common alloy is 80% nickel and 20% chromium, by weight. Silvery-grey in colour, corrosion resistant and has a high melting point of 1400 C (2552 F). Due to it's high resistivity and resistance to oxidation at high temperatures, it's widely used in heating elements, such as in hair dryers, electric ovens and toasters. Typically, Nichrome is wound in wire coils to a certain electrical resistance, and current passed through to produce heat. For heating, resistance wire must be stable in air when hot. Nichrome wire forms a protective layer of chromium oxide. Kimber :)

Why is oxygen replaced with other gases in a light globe?
nichrome is ideal as it doesn't react with oxygen or become britter when heated till red hot. love u :) xoxo
How do you make a circuit using bimetallic strip?
The bimetallic strip is made of two different metals, bonded together. The two metals have different temperature expansion coefficients, so when the bonded assembly is heated or cooled, it curves one way or the other, allowing a switch to be opened or closed.
How electric cooker works?
Electric cookers work through conduction. The electric burner is heated up and a pot or pan is placed against it. This contact allows for conduction and the content in the pot is heated in the same way.
