f=f(cos a_y - sin a_x) b) f=f(cos a_y + sin a_x) c) f=f(cos a_x + sin a_y) d) f=f(cos a_x - sin a_y) Which statement is not true about a phasor? a) It is a complex quantity b) A phasor has more than one representation c) it may be a scalar or a vector d) it is a time-dependent quantity The z-axis carries filamentary current of 10 pi A along a_x, which of these is incorrect? a) H= - a_x A/m(0, 5, 0) b) H= - 0.8a_x - 0.6a_y A/m at (-3, 4, 0) c) H= a_theta A/m at (5, (5, pi/4, 0) d) H= -a_theta A/m at (5, 3 pi/2, 0)

Solution

7) the phasor is a complex quantity ,time-dependent and it is sclar quantity .

a phsor has more than one representation .

so out of the given options (c) is not correct . because the phasor is sclar but not a vecctor. so these is in correct .
