Explain your drawing of an electrical engineer at work below.
Answers will vary, but may include: Someone who uses what they know about math and science to solve problems involving electricity.
What is an Electrical Engineer? Draw and label a picture of an electrical engineer at work.
A good picture would show someone working to solve a problem involving electricity. They may be shown using or drawing a schematic diagram or designing/improving things that involve electricity.
Examples include: someone designing or improving a power plant, telecommunication systems or devices, computers, video game systems, hand-held devices, DVD players, etc.
