Q:do you have to use a fuse link when hooking up your amp power cable to your battery?
yes, 2. I had a/c work done and when I got the truck back no radio.
Q:what happens when A power cable of copper is stretched straight between two fixed towers.?
Change in length=(coefficient of expansion)(original length)(change T)= (.0017)(chose your favoret length, I chose 100)( -128 because T is decreeing)=-21.76 Strain = (change in length)/(original length)= 21.76/100= .2176Pa (for simplicity's sake I dropped the negative, rember the wire is in tension) Stress = (youngs modulus)(strain)= (11•10^10)(.2176)= 2.3936•10^10 Pa The UTS (2.4•10^8)<(2.39•10^10) so there is definitely necking and because of the difference most likely there was failure long ago.
Q:Where the computer can be a bare chassis. Which hardware inside the framework
Depending on how much of the 24 switches that U ah, 1U, then up to 42 slightly, but still empty position good heat dissipation, 2U, then installed a 20 up to the bar.
Q:Why do we need to transpose the cable in power system?
If the adjacent line induces current in a nearby cable that would be a problem. Transposing results in one section having an induced current with a certain phase but the next section (after the transposition) has an induced current with the opposite phase. Over the length off the cable, the opposing induced currents will cancel each other out.
Q:what is the easiest way to replace the power window cables on the motor in the passenger side of a '94 accord
If you are referring to the electrical wires leading to the power window system, then you need to cut wires and splice new ones back into the system along with the plug at the end of the cable.
Q:My puppy has broken the black plastic on the outside of my laptop power cable, is it dangerous?
no its fine but i would suggest that you take caution in plugging it back in maybe wear rubber gloves or something but you shoould be fine, some people would go out and by a new cord but it is completely unneccesary
Q:What is the difference between a trough bridge and a tray tray?
Many, with the cable where the requirements should be used bridge.
Q:Outlets loosing power after hitting lower leg with cable snake.?
You may have loosened a connection. With the breaker off, check all the outlets on the circuit that's losing power and make sure all the connections are tight.
Q:Can a laptop computer be powered via USB cable?
Some lower-powered devices can be powered by USB. I believe a laptop would draw too much amperage to be powered by USB.
Q:when selecting muticore power cable the current rating of conductor in cosidered individually or total 3 cores?
Current ratings for conductors are based on several factors including conductor type (Copper, Aluminum, other), insulation material (thermoplastic, rubber, asbestos composition), ambient temperature, length, exposure to weather, and numerous other factors stipulated by the NEC or local Code. The ratings are usually given for a single conductor in free air. Mulitiple current carrying conductors which share a conduit, raceway, or any other enclosure must be derated appropriately. See the source below for Code reference and rules of thumb.
