Question

The electricity used in homes is typically 110 V, although some devices use 220 V. But electricity is transmitted long distance at much higher voltages, 110 kV, 230 kV, and as high as 500 kV. The same amount of power could be transmitted at higher currents, and lower voltages. The use of high voltages, furthermore, involves safety concerns. There is, however, a strong economical reason to use very high voltages for transmitting power, and that reason should be clear in this week's reading. Explain that reason in complete, coherent sentences.

Explanation / Answer

when power is transmitted it should be transmitted at high voltageand low current because while transmitting the heat produced around the carrier isproportional to the square of the current .hence . if current is transmitted at high voltage and low current heat losswill be less
