Although there is no general meaning, it can be used to mean that electrical engineering has a lot of importance. However, this could vary from one field to another.
If you work in an industry that manufactures UPS systems or batteries, it is important to be familiar with the basics of chemistry, especially electrochemistry. This knowledge is essential because it provides a lot the background knowledge needed for this field. An electrical engineer might need to provide chemical quantities as part of his electrical design to a chemical engineering to enable the fabrication of a new model cell or battery. There are also simulations that must be performed before prototyping can begin. It is important to have precise simulation models. These models have equations at their bases. Since you will be working with chemical components such as batteries, you need to know their fundamental quantities.
A lot of electrical engineering materials are also moving into the realm of polymers, and plastics. Again, this is a branch in chemistry. Although an electrical engineer may not need to be able to explain the process of making all polymers, it is possible to have a basic understanding of how they are made so one can choose the right materials for a particular component. A chemical engineer and an electrician will usually work together to solve these problems. However, it’s not uncommon for an engineer to be required to understand the implications of many branches.
Electrochemistry is the most common area an electrical engineer might have to deal. It is intuitive and has clear mathematical concepts. A number of quantities may also be required by an electrician, so electrochemists have created standard tables. A person who majored is Chemistry will be able to help you with any problem.
