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))
What else can I help you with?
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.
At what degrees on the sine wave is the voltage equal to zero?
On a sine wave, the voltage is equal to zero at every integer multiple of 180 degrees. This occurs at 0 degrees, 180 degrees, 360 degrees, and so on. These points represent the crossings of the waveform along the horizontal axis, where the sine function equals zero.
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.
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 the arc-sin of 45 degrees?
The arc-sine (or inverse sine) of 45 degrees is the angle whose sine value is equal to the sine of 45 degrees. Since the sine of 45 degrees is ( \frac{\sqrt{2}}{2} ), the arc-sine of ( \frac{\sqrt{2}}{2} ) is 45 degrees. Therefore, the arc-sin of 45 degrees is also 45 degrees, given that it falls within the principal range of the inverse sine function.
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 the value of sin 30 degrees?
Sine(30) = 0.5 or 1/2
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 sine of 225?
Sine of 225 degrees = - 0.5 sqrt(2)
