Document Summary
Average value of numbers (1+2+3)/3 = 6/3 = 2. Rms value: square root of 4. 67 = 2. 16. If v is a sinusoidal function then (powerpoint) V average = 0 so not helpful to calculate for sinusoidal fuctions. Average power into resistor: paverage = vrms. A source of alternating emf = ac source. Iclicker: you plug a toaster into a wall socket and turn it on. Current moving away the socket = electrons moving toward the socket. Current moving toward the socket = electrons moving away from the socket. It does not matter which way electrons/current flow there is always power. Iclicker: a small circular ring of wire is inside a larger loop of wire that carries a current. The small ring and the larger loop both lie in the same plane. If i increases, the current that flows in the small ring. Only rate of change of flux induces an emf.
