THANK YOU in advance! Parts a and b are part of the same problem.
Pre-lab assignment (a) What is a phasor in AC circuits? What does the magnitude of the phasor represent? What does the vertical (or horizontal) component represent? 1. (b) An alternating current can be represented as a phasor (rotating vector). The vector shown is rotating counter-clockwise around the crcle with an angular frequency of o-2a/ 0 sec , the angle is. Write a formula for the x and y components of the vector (a·phasor) at general time r The length of the vector is/ At time i,U)=Explanation / Answer
Q1.
part a:
phasor in AC circuits is a representation of the AC quantity in magnitude and phase format.
magnitude of the phasor is the magnitude of the AC quantity being represented by the phasor.
vertical component represents the imaginary component of the AC quantity and horizontal component represents the real component of the AC quantity.
part b:
at any time t, angle =phi+w*t=phi+2*pi*f*t
x component=I0*cos(angle)=I0*cos(phi+2*pi*f*t)
y component=I0*sin(angle)=I0*sin(phi+2*pi*f*t)
