Question

A voltage phasor is given by V=5V<p/3 Note that the angle is in this case is expressed in radians. Determine the instantaneous voltage if the radian frequency is 2 Mrad/s. Express as both a positive sine function and a positive cosine function. A voltage phasor is given by V=5V<p/3 Note that the angle is in this case is expressed in radians.

Note that the angle is in this case is expressed in radians. Determine the instantaneous voltage if the radian frequency is 2 Mrad/s. Express as both a positive sine function and a positive cosine function.

Explanation / Answer

    Given Phasor voltage V = 5/_p/3 V = 5/_60o V ? = 2*106 rad/s Instantaneous voltage as a positive cosine function will be v(t) = 5cos(2*106t + 60o )
Instantaneous voltage as a positive sine function will be v(t) = 5sin(2*106t + 60o + 90o ) v(t) = 5sin(2*106t + 150o ) v(t) = 5sin(2*106t + 150o )
