Electrical Engineering
What it is
Electrical Engineering focuses on the study and application of electricity, electronics, and electromagnetism. It involves designing, analysing, and improving the systems that generate, transmit, and use electrical power, from small electronic devices to large-scale energy networks.
Electrical engineers work on circuits, power systems, control systems, telecommunications, sensors, and electronic devices used in homes, hospitals, transport, and industry.
Their work underpins modern life, from lighting and renewable energy to smartphones, medical equipment, and communication networks.
