Household Electricity Is Supplied in the Form of Alternating Current

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.
