Q:Question about transformers and power transmission?
Power is generated at the power station and transferred to the end user your home by means of power cables. Unfortunately, some power is always lost in this transfer process. It's power NOT Voltage OR Current that is required to operate your home electrical appliance. Yes, current and voltages are involved ;but it is the PRODUCT of these two that makes up the power NOT the voltage or current individually. Power = Voltage x Current Power is lost in the cables as heat as given by your i^2R. To reduce the losses then we must reduce the current I. But, if I reduce the current and keep the voltage the same then the power will fall and my kettle/Xbox/curling tongs will no longer work at home. So, to keep the power up when reducing the current I must compensate by increasing the voltage and this means using a step up transformer. Near the homes, a step down transformer is used to reduce it back down again. Since the losses in a cable are a consequence of I^2R heating then it is important to reduce the current as much as possible when transferring power. If we assume the the resistance, R of the cable is constant, then a 10,000 reduction in power (power/10,000) gives P/10,000 = I^2 x R I^2 = Power/10, 000R I = square root of [const x 10,000] I = 100. Then using power = voltage x current reducing the current by 100 means increasing the voltage by 100 to keep the power the same.
Q:wireless Internet disconnects when power cable is disconnected why?
I am assuming that you are using windows, If you haven't done so already, right click on the battery on the right hand of your task bar and click on the power options. now, click on CHANGE PLAN SETTINGS Then click on CHANGE ADVANCED POWER SETTINGS a new window should pop up, look for wireless adaptor settings and select maximum performance, This could be your answer but then again I'm not sure what you have already attempted.
Q:What causes the power cable to my amp to smoke?
What it sounds like is you accidentally connected the wires to the wrong terminals. If current were an issue u would most likely blow a fuse. But dont rule it out, u could just need a thicker gauge power 12v line. And also remember to ALWAYS GROUND the amp. either way, if it is an amp desined for car use, youre batt would never be too much power. If it is a high watt amp, you should look into buying a capaciter. Itll help regulate voltage usage and extend the life of your batt and alternator.
Q:The difference between power cable and overhead cable
. the power cable occupies less. Generally buried in the soil or laying in the room, the channel, the tunnel, the line between the insulation distance is small, no tower, covers an area, basically does not occupy the ground space. The overhead cable is the opposite. . power cable reliability. Affected by climatic conditions and the surrounding environment, transmission performance is stable, high reliability. . the power cable has to ultra-high pressure, large capacity development of more favorable conditions, such as low temperature, superconducting power cables. . the power cable distribution capacitor larger. Overhead cable is the opposite . the power cable maintenance work less overhead cable is the opposite . the power cable electric shock is unlikely. The overhead cable is the opposite
Q:Can you use regular XLR cables for microphones that need phantom power?
Yes, you can use regular XLR cables for microphones that require phantom power. The only reason why some microphones require phantom power is because they require extra voltage flowing through the XLR cable. Condenser mics are the most commonly used mics that require phantom power, mainly because of the way the diaphram picks up sound (condenser mics pic up sound in a narrower area around the mic, yet can pick up distant sounds somewhat better). It earned the name phantom because it is invisible to other balanced (non-condensing, etc.) mics that don't need the extra power. A tech section would make it easier on most of us, because most of the important questions get lost in the typical whuz you're fav song or need lyrics plz questions that flood the section.
Q:i have 2 amps that need to go into my car can i run to power cables from the one fuse?
You will need to run a wire to each amp using a fused distrobution block as mentioned. A 60 amp fuse isn't really that big for car audio. Some amps can pull 80 amperes. This fuse is really only there to protect the power wire from being shorted.
Q:is 450W enough for a single SAPPHIRE ATI HD2900PRO that only uses one power cable ?(most 2900's use two)?
If okorder.com/ if you havent i would recommend a HD3850 or 3870 as they have similar peformace with about half the power draw
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:Amp/Sub question; power wire/RCA Cables/speaker cables placement?
Separating the power the speaker wires is not as important in a car that uses DC voltage as it is in a home system that has AC voltage. It certainly doesn't hurt anything, tho.... If you do run them across each other, keep the intersection as close to a good right angle as possible. And, air is a very good insulator, so keeping some distance between the power the speaker wires is also very good.
Q:Why does the power cable for the amp need to be ran away from the RCA cables?
A thick power wire that carries a lot of current or power has anEMF - electro magnetic field around it. This field can will pass into the RCA cables - the cables that carry sound from headunit to the amp. You want the RCA cables to be as 'clean' as they can be for the best sound signal and quality. This field will interfere with the RCA's, especially low quality cheap RCA's. causing interference and poor sound quality.
