Why some appliances perform quite when long extension cord are used?
An appliance which does not use much current will perform satisfactorily with a long extension cord. Any device which uses a lot of power (space heater, large power tools) will not perform well on a long ext cord unless the cord is large enough and rated to carry the required power.
Some electrical appliances perform quite unsatisfactory when long extension cords are used Why?
Long extension cords can result in voltage drop, causing a decrease in electrical power reaching the appliance. This can lead to inefficient performance as the appliance may not receive sufficient power to operate at its full capacity. It's always recommended to use extension cords of appropriate length and gauge to avoid this issue.
In the US what is the term for a long usually narrow extension of land within a state's boundaries like Oklahoma and Florida?
The extension of land is called a panhandle.
Is the resistance of a thermistor measured in degrees celsius?
No, the resistance of a thermistor is typically measured in ohms. The relationship between the resistance of a thermistor and temperature is nonlinear, and it is used to calculate the temperature of the thermistor in degrees Celsius.
What force slows objects moving through the air?
Air resistance
Which wire has greater resistance a light plugged into an extension cord or a light plugged directly into a wall?
Light and an extension cord. The extension cord will act as an added resistor in series. The more cord you add will only increase the overall resistance from the wall outlet. If you use a high gage extension cord, this will help reduce the resistance. But any cord will add resistance. If the gage is low, then the cord will actually heat up and you will be able to feel the heat. That is due to the resistance within the cord. Check out my sketch of how I perceive your Q: Chord + drop light w/chord ]---------------(]--------O Versus drop light w/chord ]--------O
The resistance of an extension cord varies directly with the length of the cord?
This means that as the length of the extension cord increases, the resistance also increases. Similarly, if the length decreases, the resistance will decrease as well. This relationship is described by the equation R = kL, where R is the resistance, L is the length, and k is a constant.
Is it acceptable by OSHA to plug an extension cord into another extension cord-?
You can plug an extension cord into another extension cord. A extension cord is to help make doing something easier.

When Adding an extension cord to an electrical device what are you increasing?
resistance. and also the posibility for a problem,dont use extension cords for any permanant wiring
Does a long extension cord draw more power than a short extension cord?
No. However, a longer extension cord has higher resistance for a given wire gauge or size compared to a short extension cord and the voltage at the load device may drop so low that it doesn't work properly. This may also be accompanied by a noticeable rise in the temperature of the extension cord. As a rule, use the shortest extension cord that will get the job done. If the extension cord must be long, use one that has heavy gauge wire to minimize voltage drop at the load.
Is it safe to plug an extension cord into another extension cord?
No, it is not safe to plug one extension cord into another extension cord as it can create a fire hazard due to potential overloading of the electrical circuit.
Is it safe to plug one extension cord into another extension cord?
No, it is not safe to plug one extension cord into another extension cord as it can create a fire hazard due to overloading the electrical circuit.
Does an extension cord use power if nothing is plugged into the other end?
If there is no load plugged into the cord there will be no power consumed. The only time the resistance of the cord will come into effect is when the circuit becomes energized through the load plugged into the end of the cord.
How do you ohm a drop cord?
To measure the resistance of a drop cord (extension cord), first ensure it is unplugged and not connected to any power source. Use a multimeter set to the ohms (Ω) setting, and connect the probes to each end of the cord. A properly functioning cord should show a low resistance reading, typically close to zero ohms, indicating good conductivity. If the resistance is significantly higher or shows an open circuit (infinite resistance), the cord may be damaged and should not be used.
Is it harmful to plug an extension cord into another on identical to it?
Not in general. You can buy extension cords in a variety of lengths. However, the longer the cord the more the resistance and the bigger the voltage drop across the length of the cord. If you were using the cord outdoors and the junction was on the ground it is possible for moisture to cause a short at the junction.
Why will an electric drill operating on a very long extension cord not rotate as fast as one operated on a short cord?
It is the voltage drop from the undersized wire that is used in the extension cord. Under this condition you will find that the drill will start to become hot with the additional current that the drill is trying to draw to keep the motor turning. It could get to a point where the breaker will trip before the drill burns out.
