N a us household the voltage in volts in an electric outlet


Question: In a US household, the voltage in volts in an electric outlet is given by

V = 156 sin(120Πt)

where t is in seconds. However, in a European house, the voltage is given (in the same units) by

V = 339 sin(100Πt)

Compare the voltages in the two regions, considering the maximum voltage and number of cycles (oscillations) per second.
