Hi,

Welcome to CareerGuide.com

I am confused myself, by what your question means?
Because I am very sure, you know the difference between the two fields.

Are you then here referring to:

1. Difference between the two in terms of Job roles and responsibility
2. Can both work in a same industry
3. Financially, are both paid the same or which is better paid.

As an Electronics & Instrumentation engineer, one needs to opt for 12th Science, and a PCM option, after 12th clear entrance exam and then is eligible for a 4 years B.E / B.tech course.
These are engineers mainly into manufacturing of devices needed in various fields.
As such CA is a Financial related course, dealing with accounts and taxation.
Any 12th pass, with knowledge related to Math and an interests in Accounts can opt for a CA course.

As such since CA is related to managing the finances of an organization, they can work hand in hand with an Instrumentation engineer or in an engineering or manufacturing firm.

A CA can work in an engineering firm, but not the other way round.
Also please note that as mentioned earlier any 12th can pursue CA, as an engineer too, if you have interests in Accounts and budgeting, CA can be opted.

Both at the beginning of their career are excellently paid, then depending on their years of experience, ones income would vary.

But mind you both are two extreme fields. Difficult to think of them as working in sync or parallely. One generally relates to the Science or technical field, whereas the other is purely Financial field.

Think before you make a choice.

Hope this helps you with your issue.

Wish you good luck....
