Household Electricity Is Supplied in the Form of Alternating Current

question 6

Short Answer

Household electricity is supplied in the form of alternating current that varies from 170 V to -170 V with a frequency of 60 cycles per second (Hz). The voltage is thus given by the function E(t), where t is the time in seconds. Voltmeters read the RMS (root-mean-square) voltage, which is the square root of the average value of over one cycle. Calculate the RMS voltage of household current. Round your answer to the nearest integer.
