In a us household, the voltage in an electric outlet (in volts) is given by the following equation, where t is in seconds. v = 156sin(120 pi t) however, in a european house, the voltage is given (in the same units) by the following equation. v = 339sin(100 pi t) answer the following questions comparing the voltages in the two regions.
how much greater is the maximum voltage in a european house than a us house? volts
what is the number of cycles (oscillations) per second in a us house? cycles/second
