Q:Apple mobile phone does not support this charge when charging this thing how to charge
So, from the degree of hearing up, it is not suitable for the family pet
Q:Power Cable for a keyboard?
Here are two adapters for your keyboard, your manual or a sticker on the keyboard, should tell you which one you need.
Q:Power Cable Check Well b-type covers show what?
B-grade steel fiber concrete check covers are used for motor vehicle driving, parked urban roads, highways and parking lots C-grade steel fiber concrete check covers for slow lanes, residential quarters and sidewalks D-grade steel fiber concrete inspection covers for green belts and motor vehicles can not travel, parked lanes and venues
Q:Is it my power supply or the power cable that's not working?
every power supply I've gotten for years uses completely standard, detachable power cords. I've never yet seen one that will not use the same cords as all the others. Use the one from the old supply
Q:Lost power Cable for scanner: HP Scanjet 3400C. Replace with?
You're okorder.com/
Q:Where in the US can I get power cables for the smaller electrical appliances?
try the internet
Q:Is there a telephone/power line running between Britain and America under the sea?
Satellite lol If there was a cable some kind of fish or something would of cut it by now.
Q:Is the electricity in a power cable completely lost after unplugging it?
by electricity I assume you mean electrical energy. power is the rate at which electrical energy is consumed. Power is generated by the flow of electrical current across a potential difference. Let's use an analogy. A cable is like a water pipe. Current is like the flow of water in the pipe. Pressure is like potential difference (voltage). When there is a difference in pressure at the two ends of the pipe, water will flow through the pipe. The flow of water carries energy, because it can be used to spin a paddle wheel (motor), and the friction of the water against the pipe (electrical resistance) generates heat. I think your question is something to the effect of, if I suddenly remove the pressure difference across the pipe, won't there still be energy in the water flowing in the pipe, and isn't that energy wasted? Well, there's a difference between water and electrical current: the electron hardly weighs anything. There's very, very little energy stored in the motion of electrons in a wire. When the wire is disconnected, the electrons come to a stop almost immediately, and the amount of energy wasted is infinitesimal. I hope that sort of answers your question.
Q:What power cable gauge do I use to hook up a car amplifier? Most amplifier kits appear to be under sized.?
with that kind of amp go with 8 gauge
Q:how do I wire dash lights in my car with a 302cm power cable?
I don't know what you mean by 302cm power cable. When it has 2 wires, one if usually the hot (power) and one is the ground (earth.) I don't know much else that'll help you, sorry.
