Similarities, Differences, and Overlap: Mechanical Engineering & Electrical Engineering


Most undergraduate engineering programs, whether mechanical or electrical, will have a similar curriculum in the first few years. Students will take mathematics, physics, and basic engineering principles classes before moving on to more specialized coursework. Many online engineering programs offer mechanical engineering and electrical engineering degrees, so students can choose which field they want to study as they progress through their coursework.

Both mechanical and electrical engineers need to have a bachelor’s degree accredited by the Accreditation Board for Engineering and Technology (ABET). There are many ABET-accredited online degree programs available in both disciplines which are featured in the side-by-side chart below.


There are some key differences between mechanical and electrical engineering programs. Electrical engineers typically take more courses in electronic devices and circuits, while mechanical engineers learn more about mechanical systems and materials science. However, both majors will take courses in thermodynamics, mechanics, manufacturing processes, control systems, and fluid dynamics.

Many students choose to specialize in a particular mechanical or electrical engineering area. Common mechanical engineering specializations include aerospace, automotive, biomedical, and materials science and engineering. Popular electrical engineering specializations include computer engineering, electronics engineering, and power systems engineering.


Both mechanical and electrical engineers are in high demand across various industries. Automotive, aerospace, and manufacturing companies are some of the biggest employers of mechanical engineers. Electrical engineers often work in the computer industry, telecommunications, or utilities. There are many different specializations within each field, so it is essential to do your research to find the right fit for you. Both mechanical and electrical engineering offer a variety of specializations that can lead to exciting and lucrative careers.
