Electrical and electronic engineering involves fields such as electronics, computer systems, telecommunications, bioengineering, control, robotics and electrical power engineering. Electrical and electronic engineers design and build systems and machines that generate, transmit, measure, control and use electrical energy essential to modern life. UON train engineers capable of solving the greatest global challenges. As an electrical and electronic engineer students can help develop precision agriculture technology to increase food production efficiency, refine aircraft electrical systems and even build smart grid systems to help manage alternative energy resources. Or, like researchers, could develop medical technology such as the artificial pancreas.
