They learn to connect circuits, measure electrical parameters, perform calculations, and troubleshoot. Two variants of the system are available: System includes all required components to perform the exercises of the student manual and a double-sided workstation that can accommodate an additional team of students if the second team add-on is also ordered. System 3460-A is the second team add-on and includes the same components as system 3460-A but without the workstation. It is a great way to optimize limited laboratory space. Courseware The student manual provides the necessary theoretical background and detailed step-by-step procedures to efficiently perform the hands-on exercises. A list of review questions is also available at the end of each exercise. The instructor guide has the same content as the student manual plus the answers to procedure and review questions. Topic Coverage Introduction to electricity Switches Series and parallel circuits Voltage and current measurements Ohm's law, Kirchhoff's voltage and current laws Capacitors and inductors Transformers Relays and contactors Semiconductors, diodes, LEDs, rectifiers Electrical distribution Troubleshooting Estimated program duration: 60 hours List of Available Training Systems 2 Festo Didactic
