Household Electricity Is Supplied in the Form of Alternating Current

Question 9

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 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.   over one cycle.Calculate the RMS voltage of household current.Round your answer to the nearest integer.
