Electrical Engineer
Designs electrical systems, circuits, and electronic devices — from power grids to microchips.
Did you know?
Nikola Tesla, a pioneer of the alternating current (AC) power used in homes, could do integral calculus in his head as a student. Teachers thought he was cheating.
How subjects help
- Mathematics: Calculate the current and voltage in a circuit so the wires never overheat.
- Physics: Use how magnets and coils work to design motors, generators and transformers.
- Computer Science: Program the chips that control smart devices, from thermostats to electric cars.
- Chemistry: Understand how batteries store charge and choose materials that carry electricity well.
A famous name
Nikola Tesla: Electrical engineer who developed the alternating current (AC) motor and power systems used worldwide.
Try it yourself: Draw a circuit and trace the power
- Draw a battery, a switch and a bulb, then join them with lines to make one loop.
- Trace the path with a coloured pen from one end of the battery, through the bulb, and back. A bulb only lights when the loop is complete.
- Draw a second circuit with a gap in it. Would that bulb light? Why not?
- Add a second bulb. Can you draw it so one switch controls both? Only draw it: never experiment with mains electricity.
Electrical engineers design circuits on paper and on computers long before anything is built, so every path works safely.
