Web7 feb. 2006 · Electric power is generated at relatively low voltages, 25 kV or less. It must be transformed to a higher voltage for transmission, then transformed down to the distribution voltage, typically less than 25 kV. As the cost of the transformers also increases with voltage, the optimum voltage must be chosen carefully. WebWhen the phone rings, the signal is a 20 hertz AC signal (about 90 volts). When in use it is a modulated DC signal (between 6 and 12 volts). The phones lines even have power during a blackout in most cases. This is because the phone company maintains their own backup power system.
