Electrical sockets (outlets) in the People's Republic of China usually supply electricity at between 220 and 240 volts AC. If you're plugging in an appliance that was built for 220-240 volt electrical input, or an appliance that is compatible with multiple voltages, then an adapter is all you need.
Similarly, an increase of 3 dB implies an increase in voltage by a factor of approximately â2, or about 1.41, an increase of 6 dB corresponds to approximately four times the power and twice the voltage, and so on. In exact terms the power ratio is 10 6/10, or about 3.9811, a relative error of about 0.5%.imilarly, an increase of 3 dB implies an increase in voltage by a factor of approximately â2, or about 1.41, an increase of 6 dB corresponds to approximately four times the power and twice the voltage, and so on.
