DC Fundamentals FACET Board



The DC Fundamentals course provides comprehensive, hands-on instruction in the terminology, principles and applications of dc circuits. Following a carefully designed instructional program, students become familiar with all components of the board. They learn how to isolate, identify, and test a series of circuits and perform troubleshooting exercises to demonstrate their mastery of the course objectives.

All dc power to the circuit board is supplied by the 15 V power supply via the base unit and its protection circuitry. Students troubleshoot dc circuit faults inserted by the computer or manually by the instructor, who alters hidden switches located under a locking cover.

A dc milliammeter is provided with the circuit board.

The circuits found on this board include:

- Batteries

- Switches

- Ohm’s Law

- Series Circuit

- Parallel Circuit

- Series-Parallel Circuit

- Power

- Linear/Non-Linear Variable Resistor

- Voltage Divider

- Voltmeter/Ammeter/Ohmmeter
