And though he was against capital punishment, he created the first electric chair for New York to show how much deadlier AC was than DC. Edison was correct in that AC power can be deadlier than DC at similar voltage levels because the frequencies of the voltages can interfere with the beating of the heart. However, at high voltages both AC and DC power are deadly. His demonstrations were more propaganda effort than real actual science. 45 A ND THE WINNER IS ... Note that in both cases, the power plant is generating the same amount of power: 10kW.

Why are high voltage lines run through the air? You may be wondering why these lines are run through the air and not buried deep underground. This is because at these high voltages, the amount of insulation required to cover the wires to keep them from touching the ground would be financially impractical. Also, the wires would have to be buried very deep in order to keep someone from digging into them. And finally, if there is an electrical issue, such as a broken wire, it’s much easier to fix a wire that is exposed instead of one you cannot easily see where the break might be.

Both AC and DC are methods for distributing power. However, as the power requirements of the load changes, both attempt to maintain their voltage values. For example, in your house, the AC voltage coming in is always at a (relatively) fixed 230V AC. Over time, the power requirements of your house change as electrical appliances turn on or off. This means that the resulting alternating current generated by this voltage may be higher or lower at any given point in time. If no electricity is being used, then no current flows into your house.
