  • Generating Electrical Voltage

    In this interactive resource adapted from the Wisconsin Online Resource Center, learn how a generator converts mechanical energy into electrical energy. Investigate the principle of magnetic induction by moving a conductor through a magnetic field to see how voltage is generated. Explore factors that influence the amount of voltage generated, such as the angle, speed, and length of the conductor and the strength of the magnetic field. In addition, learn the left-hand rule that describes the relationship between the motion of the conductor, the direction of magnetic flux lines, and the direction of current flow.

  • ATE Internships and Co-ops

    This video adapted from ATETV introduces viewers to internships and cooperative education programs, or "co-ops." These two types of work experience—one part-time, the other full-time—help prepare students for careers in technology and engineering. Bristol Community College encourages its students to do internships and co-ops in order to gain hands-on experience and apply classroom lessons in the real world. Because internships and co-ops allow students to work with the actual equipment and technology used in industry, this can help students get hired by employers as soon as they graduate from their school or certificate program.

  • Water Treatment Technician

    Tour a water desalination plant, where brackish water (a mixture of freshwater and saltwater) gets turned into pure freshwater in this video adapted from ATETV. Plant worker Michael Poitras, who started working at the plant as a community college intern, describes the filtration process that progressively removes salt and other impurities from the water. He also explains the coursework needed to prepare for a job in a water treatment plant, and how the desalination process can be used in other parts of the world, especially in highly populated areas where freshwater drinking supplies are depleting.
