What is the furthest distances that we can transmit electrical energy?

Answer 1

We are receiving electromagnetic radiation from the borders of the observable universe, so the answer is whatever distance light travels in the allowed time. If that's not what you're asking, clarify your question.

Answer 2

Telescopes pick up electromagnetic radiation from billions of light years away, if that is your question.

If your question is about the electrical transmission and distribution grids, is depends on the voltages, wire, and acceptable losses. A significant portion of electricity in California is imported from Washington State, travelling over 1000 miles to southern California. Typical losses in Electrical grids are 7%. There are backbone 500kVAC and 800kVDC transmission systems that run the length of California.

If you have a 20A circuit at your house with #12 wire, you will have problems if your motor is more than 300-500' away. (too much voltage drop for sufficient starting torque)

Computer circuits are limited to tiny distances due to timing issues. Electricity travels only the speed of light which is about 1 foot in a nanosecond. Sub nanosecond computers require shorter distances.

Answer 3

Electrical energy can be transmitted in the form of microwaves over great distances. It has been suggested that power plants could be built in space and beam the energy back to earth this way. Pity the bird who mistakenly transits the beam, though (it would be cooked pretty quickly).

Answer 4

If your talking about from a power plant, it really depends on how much you are willing to loose. Transmitting electrical energy wastes a lot of energy through heat, resistance, ect. We can send it for 100s of miles, but 100% of what we sent doesn't get there... well uless we superconduct the wire with liquid helium with a liquid nitrogen, you can send it for unlimited distance w/o any loss.

Answer 5

enable's say the means plant is providing 1KW on your place at 100V (not 110V in order that as that the calculations are less complicated) the present required to try this 1000W/100V = 10 A enable's say the resistance of the cable from the powerplant on your place is 5 ohms. You woud have misplaced I^2R watts in the transmission, ie., 10 * 10 * 5 = 500 W misplaced. With AC that's amazingly ordinary to step up or step down the voltage utilizing transformers. once you are trying this, if V1 and I1 are the enter voltage and cutting-edge, and V2 and I2 are the output voltage and cutting-edge, then for the transformer, V1*I1 = V2 * I2 enable's say the means plant steps up the voltage to ten thousand V after which in basic terms in the previous achieving your place, steps it right down to one hundred. the present ate up at your place at 100V is 10 A hence 100V * 10 A = 10000V * x A the place x is the present alongside the transmission line x = one hundred * 10/ten thousand = 0.1A returned, assuming the line resistance became into 5 ohms, the entire means wasted alongside the transmission line is I^2R = 0.a million * 0.a million * 5= 0.05 W while in comparison with the previous occasion the place 500 W became into misplaced turning in one thousand W on your place. that's a touch simplistic image, yet oftentimes illustrates why AC is extra effective thanDC, the place you may't effectively and unquestionably step up and step down the voltage.

Answer 6

If you are talking transferring electrical power via the power grid for consumers.....
it gets pretty inefficient to move it more than 400 miles or so using alternating current, and even that's at very high voltage.

Using direct current, it gets inefficient to try to move it more than a mile.

Edison wanted to use DC. Tesla thought AC was better, and Westinghouse agreed. The power grid went up as AC because that's what works.

Answer 7

Pretty close to infinite if you have enough time for the waves to travel through space.
