Web11 jan. 2024 · Power lines have slightly higher resistance for AC than for DC due to the skin effect. The wiki article has extensive information on your question, including the AC vs. DC resistance of round wires. In practice, as power wires are stranded, the skin effect losses can be kept very small. Web5 mei 2016 · If he's talking about a transmission line then AC impedance at high frequency can be very high (open circuit) or very low (short) at certain points depending on the inductance, capacitance, resistance, frequency of the signal and other such things. – squarewav May 5, 2016 at 3:12

AC or DC - Which One is More Dangerous And Why
Web12 aug. 2024 · Therefore, in DC, there is no advance or delay in the circuit. In alternating current (AC), the direction of the current is switched, so not all the electricity passes through the load, and some power is generated just traveling back and forth between the load and the power source. This is called reactive power. Web7 mrt. 2024 · Whenever power has to be transmitted over long distances, DC transmission is the most economical solution compared to high-voltage AC.
