They get red-hot, but the fuse does not blow, nor the breaker trip. Lower resistance wire fed with 120 volts might draw enormous current and get red hot, but the fuse would blow, or the breaker trip.
Of course, You could always whip out your trusty multimeter and measure the resistance (allowing for change with temperature rise of course). Or, you could measure the voltage, then the current, then divide voltage by current to get resistance (at operating temperature).

How can you tell the difference between positive and negative wires?
One way to tell the difference between positive and negative wires is by their color coding. Positive wires are typically red, orange, or another bright color, while negative wires are usually black or another dark color. You can also use a multimeter to test for voltage: the positive wire should show a higher voltage than the negative wire when tested.
How can you tell there is friction and resistance in a bulb?
Electrical resistance is technically not the same as friction though one could be used as a model for the other. Electrical resistance in a light bulb can be seen by the light that is emitted due to the heating of the filament when current is passed through it (electrical potential is transformed into heat).
What is the resistance if the current is 0?
If you measure zero current, then there are two possibilities,and there's no way you can tell which one is true withoutanother measurement.-- The voltage across the circuit may be zero,and the resistance could be anything.-- The resistance of the circuit may be infinite,and the voltage could be anything.
How can you tell if an object is a conductor or insulator?
you can use a multimeter (a.k.a VOLTMETER) attach the wires to either sides of the object if you get a reading on the screen or if the needle moves than you know that it is an electronic conductor
Describe the purpose of the coloured bands on a resistor?
The colored bands on a resistor indicate its resistance value and tolerance. By interpreting the color code, you can determine the resistance value of the resistor and the range within which the actual resistance may vary. This helps in identifying, sorting, and using resistors in electronic circuits.
How can you tell if you need new spark plug wires?
You can test their resistance with an ohmeter to see if within spec. It is so much per foot and if exceeds that, replace.
How many meters of wire make one ohm?
The resistance (ohms) of a conductor depends on a number of factors including the type of material, its thickness and the temperature. There are charts that will tell you the resistance of different sizes of wires and the correction factor to use for non-standard temperatures.
How do you connect copper wires to battery?
i will tell you how if you tell me what this project is called,it uses light bulb, copper wires,holder,6 volt battery.
What is on the back of a gm steering pump with two wires?
High pressure switch and or high temp switch. The high pressure switch is to tell the engine computer of the extra load to improve drivability. Not having one could lead to engine stalling in tight turns.
How do you tell the colored wires in a 94 dodge spirit?
You dont
Will their be a resistance 3?
hello, i am actiually part of the PS3 team working on resistance and what i can tell you is that, yes we are currently starting work on a resistance 3.
How do you tell if you have a V4 or V6?
Count the number of spark plug wires.
How much energy does a large size Oster toaster oven use?
Large does not tell us much. However the rating will be printed somewhere on the appliance.
How do you tell which wire is positive or negative on a cars headlight?
Check the wires with a multimeter.
Do the mutant aliens from resistance eat people?
== == does any body know if ALIENS from resistance eat people and animals cuz if they do then tell me and ill tell every body i know and then they can tell the people they know and the people they know and so on. ok then later dudes

How do you tell if a 1999 Isuzu amigo is a 4 or 6 cylinder?
Count the sparkplug wires.
