8–96 AC Circuit Analysis Ten years after graduating with a BSEE, you decide to go to graduate schools for a master’s degree. In desperate need of income, you agree to sign on as a grader in the basic circuit analysis course. One of the problems asks the students to find vðtÞ in Figure P8–96 when the circuit operates in the sinusoidal steady state. One of the students offers the following solution:

Is the answer correct? If not, what grade would you give the student?
If correct, what comments would you give the student about the method of solution?

v(t)=(R+ joL)xi(t) =(20+ j20) x 0.5 cos 2001 = 10 cos2001 + j10 cos 200 =102 cos(2001 +45)
