Product Overview: AC Circuits Trainer 301-ACC
Product Training Topics & Objectives
The system guides students through eleven core AC electronics milestones :
-
- Waveforms: Tracking frequency, period, peak, and RMS values .
- Resistive Loads: Monitoring AC voltage drops across series and parallel resistor banks.
- Square Waves: Inspecting reactive components under square wave inputs.
- Capacitive Loading: Computing phase shifts and capacitive reactance (\(X_{C}\)).
- Inductive Loading: Measuring phase angles and inductive reactance (\(X_{L}\)) .
- RC Circuits: Finding total impedance (\(Z\)) in mixed resistance-capacitance grids.
- RL Circuits: Analyzing phase shifts in mixed resistance-inductance setups .
- RLC Circuits: Finding resonant frequencies, Q-factors, and dynamic impedance .
- Filter Networks: Calculating cut-off/corner frequencies for high and low-pass filters .
- Transformers: Studying turns ratios, winding configurations, and impedance matching .
- Safety Isolation: Using isolation transformers to safely ground floating chassis test setups.
Product Overview: AC Circuits Trainer (Order Code: 301-ACC)
The AC Circuits Trainer is a modular educational hardware and software system designed by LJ Create (p. 1). It provides comprehensive, hands-on training in alternating current (AC) electronics and diagnostic troubleshooting .
