Electricity and Electronics Level 2 - Tech-World
Students begin Level 2 by studying industrial motor controls. They connect circuits containing industry standard components such as switches, starters, relays, and transformers, and describe and demonstrate their operation as well as typical applications.
Next, they identify different control pilot devices and their symbols, and demonstrate their uses and functions by connecting them in simple circuits. Students use wiring diagrams to construct and demonstrate two-wire and three-wire control circuits, and learn how to distinguish between two-wire and three-wire pilot devices.
Students then progress to the advanced topics of semiconductors, operational amplifiers, and thyristors, using the award winning FACET program in conjunction with tools such as a digital multimeter and oscilloscope. They learn to explain the composition and operation of semiconductor diodes and transistors, and demonstrate how they operate in both ac and dc circuits.
Students continue their studies with a different family of semiconductor devices called thyristors, and demonstrate how they can be used in various kinds of ac and dc switching and control circuits. Students learn to calculate and measure the input and output signals and circuit gain of inverting, non-inverting, and summing operational amplifier circuits. In addition, they set-up and adjust a voltage divider and attenuator circuit to provide specific input voltages to the op amp circuits.
Finally, Level 2 introduces the students to digital logic gates and flip-flops, the fundamental building blocks used in today's high-speed digital computer and control circuitry. Students monitor and analyze logic states using the FACET system. They then draw basic digital circuits using Circuit Maker Pro? and simulate their operation.
