If you have V = 120Vrms Cos(2*pi*60t + 120). The magnatude of the voltage is 120Vrms. The frequency is 60Hz. The phase shift is 120. That would be the voltage that comes out of a standard American household eletrical outlet. The current would depend on what is plugged into the outlet. A general equation would be VmCos(w*t + theta) or ImCos(w*t + theta) for current. To use a Sine wave, just do a 90 degree phase shift. (sin(t) = cos(t-90) or cos(t) = sin(t+90))
The voltage and current sine waves cross the zero line at the same time and going in the same direction. The phase angle is 0°. They are said to be in-phase.
The voltage and current are delivered in a sine wave that goes positive and then negative at 60 cycles per second. Google sine wave to see what a sine wave looks like.
Sine wave
A one diode rectifier is called a half wave rectifier and only allows current flow for the positive portion of the sine wave. A two diode rectifier, or full wave rectifier allows positive current flow during the positive portion of the wave as well as positive current flow during the negative portion of the sine wave. This results in a much cleaner DC power signal. The addition of a capacitor in the output circuit will clean up the signal very nicely.
A: Since it can be considered a full circle then then there will be 4 quadrant for 360 degrees
The sine of 75 degrees is about 0.9659
It's not. The sine of 32 degrees is approximately 0.53. The sine of 59 degrees is approximately 0.86. For a definition of sine, see: http://en.wikipedia.org/wiki/Trigonometric_function .
The sine of 22.5 degrees is 0.383
sine-1(0.3420201433) = 20 degrees
sin77 = 0.974 Therefore the sine of 77 degrees is 0.974
The sine of 52.5 degrees equals 0.79335334029124. Hope I helped!
sine 40° = 0.642788
sine(15 degrees) = 0.25882 (rounded)
Sine of 225 degrees = - 0.5 sqrt(2)
No. The sine of an acute angle is less than 1. An acute angle is less than 90 degrees. The sine of 0 degrees is 0, and the sine of 90 degrees is +1. So the sines of the angles between 0 degrees and 90 degrees are less than 1.
sine of 30 degrees
Sine 3.3 degrees is about 0.057564. Sine 3.3 radians is about -0.157746. Sine 3.3 grads is about 0.051813.
