## AC Voltage at home is 230V but its equation is v=Vm Sin φ. Explain the difference?

Our homes are supplied with sinusoidal voltage whose equation should be (v=Vm Sin φ). But we always say that A.C. voltage at home is 230 V. how do you explain this difference?

Average value of Alternating Current means average value of whole period T (in Europe T = 0,02 [s]) and RMS value is an amplitude of current divided by square root of 2 🙂

2. WASIM KHAN says:

Coz AC Current and Voltage has Frequency..When EMF induce in AC alternator , According to AC concept ( DC has not frequency while AC Has..) There Will be frequency…. And the concept of 60 and 50 Hz…that where it came from….? remember the famous formula Ns = 120f/P … or f = 120 /(PxNs).
