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))

How many degrees are the current and voltage out of phase with each other in a pure resistive circuit?
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.
Why is the electric current you receive at your house is called alternating current?
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.
What is the diagram of ac current?
Sine wave
What is the difference between a one diode rectifier and a two diode rectifier?
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.
How many alternation does a sine wave contain?
A: Since it can be considered a full circle then then there will be 4 quadrant for 360 degrees
What is the sine of 75 degrees?
The sine of 75 degrees is about 0.9659
Why is the sine of 32 degrees greater than the sine of 59 degrees?
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 .
What is sine of angle 22.5 degrees?
The sine of 22.5 degrees is 0.383
What is the sine of 20 degrees?
sine-1(0.3420201433) = 20 degrees
What is sine for 77 degrees?
sin77 = 0.974 Therefore the sine of 77 degrees is 0.974
What is the sine of 52.5 degrees?
The sine of 52.5 degrees equals 0.79335334029124. Hope I helped!
What is the sine of 40 degrees?
sine 40° = 0.642788
What is the value of the sine ratio for the angle 15 degrees?
sine(15 degrees) = 0.25882 (rounded)
What is sine of 225?
Sine of 225 degrees = - 0.5 sqrt(2)
Is the sine of an acute angle is greater that 1?
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.
What is the value of 30 degrees?
sine of 30 degrees
What is the value of sine 3.3?
Sine 3.3 degrees is about 0.057564. Sine 3.3 radians is about -0.157746. Sine 3.3 grads is about 0.051813.
