Does RCD works on DC system?
Yes.but you should use DC RCD
Why is DC power transmission current high?
Power transmission by AC or DC always uses high currents, but maybe you are questioning why a DC system used very high currents. Imagine a DC system supplying a few streets at 200 volts, each house draws a current and the total current for the locality is found by adding the currents. Maybe it's 1000 amps. That is the same with AC. Now suppose several localities are supplied, each drawing 1000 amps. With a DC system the total currents still add up so there might be many thousands of amps to be supplied, needing very thick wire. But is it's an AC supply, each locality could have its own transformer supplied from a high voltage supply like 11,000 volts. So instead of many thousands of amps, the high-voltage supply might only have to carry 100 amps on relatively thin wire. The difference between AC and DC is that transformers cannot be used on DC supplies.
What type wire is best for automotve DC current?
Copper or aluminum AWG. As for gauge and such, it depends on how much amperage you have running through it, and the length of wire.
Which wire is the neutral wire in a 110 volt system?
White.
What is the difference in the direction of the magnetic field produced around conductor by dc flow and ac flow?
The direction and amplitude of the magnetic field around a wire depend on the direction and amplitude of the current through the wire. When the wire carries DC, the direction and amplitude of the current in the wire are constant, so the direction and amplitude of the magnetic field around the wire are constant. When the wire carries AC, the direction of the current in the wire is periodically reversing and its amplitude typically changes, so the direction of the magnetic field around the wire is periodically reversing and its amplitude is typically changing.
How do you get -48v DC?
In a 48V DC system you ground the positive to 0V so the live wire will be -48V.
Explain the comparison between dc 2 wire system and ac single phase 2 wire system and ac 3 phase 3 wire system and ac 3 phase 4 wire system?
of all of dem 3 phase 3 wire is most economical as it uses less conductor dan in 4 wire system, 3 phase 3 wire is used in transmission and 4 wire in distribution as it has 3 live and one neutral wire. 3 phase needs lesser conductor size than 2 phase 4 wire for the same power. 3 wire dc feeder is more economical than 2 wire dc feeder for the same power. that was all i cud get..... hope u find it a lil helpful.
How do you wire -48v dc power and ground to earth?
always think of any supply system so : RED = MOST POSITIVE BLACK = MOST NEGATIVE in a telecom system the -48V supply is refferenced to ground and earth, so the supply wire is NEGATIVE, this means a DC supply most positive signal the RED wire, go to EARTH = ZERO, the BLACK wire is the MOST negative, so in this case it is -48V
What is the common wire color?
green <<>> In North America the common (neutral) conductor is white. The ground wire is green or bare depending on its location in the system.
In dc electric Which wire is positive?
Brown
A DC ground wire coming from a power supply output is typically what color?
Typically black. DC +ve wire color typically red or brown.
What is the gauge of wire for a 13.8 dc power cords?
You need to know the current to determine the wire gauge.
How do you wire computer fan into car amplifier?
Cant. Fan on computer runs on house current (power) which is AC and the car has a DC (direct current) power system.
What has magnets and coils of copper wire?
Some DC motors.
How a 3 phase 3 wire rectifier system operates?
rectifiers are used to recrify ac to dc, I'm ot sure that you would use dc for any large voltage, though 3 phase electrics are used in commercial equipment.
What instrument measures both ac and DC?
hot wire ammmeter or a moving iron ammeter will work for ac and dc.
Is the tester can check DC in a wire?
DONT ASK FOOLISH QUSTIONS
