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.
What else can I help you with?
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.
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.
Why should you not plug a surge protector into an extension cord?
As long as you don't over load the wall socket you can have a mile's worth of extension cord. <<>> You can not have a miles worth of cord as the voltage drop would be so high on a #14 wire that there would not be enough voltage to run the computer. Make sure that the extension cord has a ground wire in it so that the ground wire is continuous from the receptacle to the surge protector to the computer.
How long can you run an electric extension cord?
It depends on the gauge of the wire, the length and the total current draw of the appliances. You said "heavy duty outdoor extension cord" so I'll assume 12 gauge wire. You can run a MAXIMUM of 20 amps for a MAXIMUM of 100 Ft on that wire. If the current draw goes up, so should the wire size. If the distance goes up, so should the wire size. 10 Ga wire - 30 amps for 100 Ft.
Why is it important that the resistance of an extension cord used to power an electric heater be kept low?
An electric heater is one of the high-power appliances in a house, commonly taking 1.5 to 3 kilowatts of power. The current is high, and therefore there is a drop in the voltage applied to the heater equal to the current multiplied by the resistance of the cord. There is probably little power wasted, because any heat from the cord goes to heat up the same room. But a voltage drop causes the heater to draw less current because its resistance is constant, and therefore less total power is provided to heat the room. If the heater is thermostatically controlled so that it is not working all the time, the difference is small because any reduction in the heater's power would cause the thermostat to keep it going for longer, to compensate.
Is it safe to plug a space heater into an extension cord?
It is generally not safe to plug a space heater into an extension cord. Space heaters draw a lot of power and can overload the extension cord, leading to a fire hazard. It is recommended to plug space heaters directly into a wall outlet to ensure safety.
Is it safe to plug a heater into an extension cord?
It is generally not safe to plug a heater into an extension cord because heaters draw a lot of power and can overload the cord, potentially causing a fire hazard. It is recommended to plug heaters directly into a wall outlet to ensure safety.

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.
Can you connect a 6 outlet power bar to an extension cord?
There are several variables:First and most important, what will be the current draw? If the total number of amps exceeds the rating of either the power strip or the extension cord you're creating a fire hazard.Second, the wire gauge and length of the extension are important. You will loose voltage over distance and that is a function of the current draw, wire type and wire gauge. If you're trying to run 20 amps, don't use any less than a 12 gauge extension cord up to a maximum of 100 Ft. 15 amps, minimum 14 gauge.

Is an electrical extension cord the same as a wall outlet?
The extension cord will extend the power outlet from a wall socket. The voltage will be the same at the end of the cord as it is from the socket. Be aware that extension cord may have a limit, as to how much current it can provide. The cord should be thick enough to provide as much power as the outlet can. It will then be properly protected by the circuit's fuse or breaker. A thin cord may get hot if a large consumer is plugged in, unless the cord is protected by it's own fuse at the plug end.
How many appliances can you run from an extension cable at once?
The total load applied to an extension cord is governed by the wire size of the cord. As the extension cord is usually plugged into a wall receptacle. The breaker protecting the receptacle is rated at 15 amps. The total wattage is limited to 15 x 120 volts = 1800 watts. Check the nameplate on the appliances to see what the wattage draw totals. This will give you the answer, any amount that adds up to the total of 1800 watts.

How does a bicycle headlight work?
Pretty much like a strangely shaped torch - with the added extension that sometime they draw their power from a generator on the bicycle
