Performance-Based Assessments for DC Circuit Competencies

Students may either use ready-made inductors for this experiment (the larger the value, the more impressive the light flash!) or inductors of their own making (using old solenoid valve coils, or hand-wound coils around steel bolts). Power transformer primary windings also work well for this.

You will need an inductance meter in your lab to do this exercise. If you don’t have one, you should get one right away!
