Ten years after graduating with a BSEE, you decide to go to graduate school 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 \(v\) ( \(t\) ) in Figure P8-76 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+ jaL) x i(t) = (20 + j20) x 0.5 cos(2001) = 10 cos(2001) +j10 cos(2001) = 102 cos(200t +45)
