![Household electricity is supplied in the form of alternating current that varies from 160 V to -160 V with a frequency of 50 cycles per second (Hz). The voltage is thus given
by the equation
E(t) = 160 sin(100nt),
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 [E(t)]² over one cycle.
