Mell Why does AC travel further than DC?
AC and DC a simply the same energy (electricity) and travel equal distances through conductors just as easily as each other. The reason we have used an still use AC for long distance transmission is because it is so much easier to step the voltage up at the generator and down at the use end than DC is.
Why does DC current not travel long distances?
DC is more efficient than AC at high voltages and has lower line losses. The line has lower losses, no reactive power is needed, and the power flow can be fully controlled. When transmitting power over distance we want to use higher voltages and lower current.
Why does AC current go further?
To understand the composition of the AC wave, you need to understand that electrical currents come from a flow of electrons. The wave-like motion of AC power gives this electricity form an advantage over DC power. Because it moves in waves, this electricity format can travel farther than DC power.
Can DC current travel long distances?
Alternating current (AC) is the type of electric current generated by the vast majority of power plants and used by most power distribution systems. Although for very long distances (more than 1000 km), direct current can often be better. …
Why do we use AC for long distance power?
Transmission Options Power can be transmitted using either alternating current (AC) or direct current (DC). All modern power systems use AC to generate and deliver electricity to customers through transmission lines and then through distribution lines to where it is needed. The technology now exists to use DC for bulk power transmission.
Which is more stable AC or DC power?
Today our electricity is still predominantly powered by alternating current, but computers, LEDs, solar cells and electric vehicles all run on DC power. And methods are now available for converting direct current to higher and lower voltages. Since direct current is more stable,…

Why do DC lines carry more power than AC lines?
DC lines can carry more power ( actually power lines do not carry power at all it is carried in the space around the wire as electromagenitic fields ) because a major limit of lines is the peak voltage they can carry before break down. AC spends a lot of time “off peak” but DC is always at its peak.
