(Recall the phasorrotates CCW around the origin and the speci±cvalue of any quantity at a given instant in timeis the projection onto the y-axis.)At the instant shown, compare themagnitude of the voltage across the inductor,Grade clustermProblemsProblemsPrint Assignment ViewWorked ExampleAC Circuits-- Optional --Limited Attempt Item ClusterImpedance TriangleScore Threshold: 100.0Remaining attempts: 0Limited Attempt Item ClusterPhasorsScore Threshold: 100.0Remaining attempts: 2Interactive ExampleAC Circuit (I.E.)ExerciseAC Circuit IExerciseAC Circuit IIDeadline:100% until Monday, December 4 at 10:00AMUnit 19: OpenStax 14.5 - 14.6 / Prelecture /Checkpoint / Homework /ZJUI Physics 212 Fall 2023CoursesAccount
