its casing will dry out, crack and catch fire, or it will crack off and cause arking, which can cause a fire... ultimately, check the gauge size of the circuit and make sure it corresponds to the proper amperage of breaker, if this is all good, you need a bigger cord(the gauge size must be sufficient for the intended tool/device.. a drill that has a 16 amp rating needs a 12 gauge cord whereas a 12 amp drill needs only a 14 gauge cord.
copper?
it is the coiled wire that heats up and gives off light in a incandescent (ordinary) light bulb.
No, not in the North American electrical system. Opening up a neutral on a three wire circuit could create a series circuit if two devices are plugged into the same receptacle. This is how kitchen counter receptacles are wired in all new homes.
About 660 watts. A hair dryer has a small blower motor and a resistance winding that heats up. The formula is watts = volts x amps x power factor. In the case of a resistive load like the wire that heats up the PF = 1. However, the blower will have a lower PF of about .8.
making a twisted up, sometimes useless piece of wire into a straight piece again.
copper?
If a person ties a piece of copper wire at the end of the exhaust pipe on a vehicle the copper is going to heat up. When the copper heats up it will turn a rainbow of colors.
The energy in a pop-up toaster comes from electricity. When the toaster is plugged in, the electrical current heats up wires inside the toaster, which in turn heats the bread or other items placed inside.
A kettle has electrical energy when it is plugged in and heating up water. It also has thermal energy, as it heats up the water inside.
No. Hook up the power wire first, then the ground wire. The ground wire is what acutually draws the power to the unit. As you will notice the power wont turn on if just the power wire is plugged in..
A High resistance wire, such as NiChrome; the wire heats up when amperage flows through.
It decreases
Yes, the fan spins to cool it down
the metal inside the wire heats up leading to the expansion of the wire.
it is the coiled wire that heats up and gives off light in a incandescent (ordinary) light bulb.
Water heats up inside a kettle when it is placed on the stove or plugged into an electrical outlet. The heat source, whether it be gas flames or an electric heating element, transfers energy to the water molecules, causing them to move faster and increase in temperature.
The piece of coiled wire made of Tungsten (Wolfram) that heats up and glows in the lamp.
