Performance-Based Assessments for Basic Electricity Competencies

Use a variable-voltage, regulated power supply to supply any amount of DC voltage below 30 volts. Specify a standard resistor value, somewhere between 1 kΩ and 100 kΩ (1k5, 2k2, 2k7, 3k3, 4k7, 5k1, 6k8, 10k, 22k, 33k, 39k 47k, 68k, etc.).

An interesting “twist” on this exercise is to specify the value of resistor R₁ in colors. For example: Red, Vio, Red, Gld instead of 2.7 kΩ.

The purpose of this exercise is to ensure students can make good solder joints on a printed circuit board.

The purpose of this exercise is to ensure students can solder a good wire splice.
