Chapter 6.6, Problem 62E

To determine

(a)

To find:

The voltage phase for generators and the phase difference if the voltage for each generator is modeled by $E_A=50\sin \left(120\pi t\right)$ $E_B=50\sin \left(120\pi t-\frac{5\pi }{4}\right)$.

To determine

(b)

To state:

Whether the generators producing voltage in phase and find the angle of the armature in the second generator to be rotated counter-clockwise in order that the two generators produce voltage in phase.
