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.

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.
Can a 15 amp extension cord be plugged into a 20 amp breaker?
A 15 Amp extension cord can be plugged into a 20 Amp circuit. It is important that what you're extending does not require more then 10-12 Amps.
What are the parts of extension wire?
There are several parts to an extension cord. There is the "female" end where you would plug in the appliance, the cord, and then the "male" end which gets plugged into an outlet.
Can a microwave be plugged into an extension cord?
Yes, as long as the extension cord is rated for the load. Most microwave ovens use 1000W or more, some less. A standard two wire extension cord would be unsafe. There are, however, extension cords which have the proper gauge of wire and the necessary 3-prong outlets which a microwave would need to operate safely.
Can an extension cord plugged on a 230V socket outlet be used to connect a fully wired container with a distribution box?
You should know the maximum current drawn from the distribution box (in amps) and that must be less than the current that the extension cord is able to supply.

Is it safe to touch a extension cord while its plugged in?
Yes, it safe to touch a extension cord while its plugged in.

Can you plug in an iPod touch wall charger to an extension cord?
Yes, you can put the iPod Touch wall charger into an extension cord. That extension cord has to be plugged into a wall to be able to charge the iPod, though.
What is the resistance of a hair dryer that draws 12A when plugged into a 220V line?
Your hair dryer has a resistance of 220/12 = Ohms. (I'm sure you can do the math.)
Is high electrical resistance good or bad?
electrical resistance is when something resists the electrical current .. eg rubber hope it helped
An electric clothes dryer has a resistance of 16 ohms It draws 15 A of current What is the voltage in volts of the wall outlet that it is plugged into?
We know that Voltage = Current x Resistance, so if E = I x R, then E = 20 x 12 = 240 volts, and the dryer must be plugged into a 240 volt outlet.

What will cause a block heater cord to catch fire?
A break in the electrical wiring inside the cord - usually it is right by the male end that you are plugging in to power - so a replacement end can be put on the block heater cord ( those flames sure can startle a person ! ) After it happened to me , I always made sure that I plugged my block heater cord into my extension cord before I plugged my extension cord into the electric outlet

Which devices should not be plugged into a UPS?
Answer: Any device which exceeds a computer's VA/Watt rating should not be plugged into the outlets. Most printers can be plugged into a power strip. A laser printer, however, should be plugged directly into the wall.
