Electrical Circuits 60-070 ECT

The ECT Electrical Circuits option introduces two additional modules; the Three-phase Switched Capacitor Load 67-212 and the Three-phase Switched Inductor Load 67-312. These are used in conjunction with the 67-142 Three-phase Resistor Load (supplied in the 60-070 Core System) to provide a comprehensive introduction to dc, single and three-phase circuits. Curriculum coverage includes Ohm’s law, series and parallel circuits, resistance, reactance and impedance, phase relationships, balance loads and dc and ac power.
