Correspondence course in BE or BTech is not recognized by the Indian government. So, you can't apply for government jobs in the future.

As per my knowledge, electrical is a practical subject. So, you might not have the option of distance. You will have to take the regular classes, rest you can still confirm from the college authorities. Yes, it might though be the case that the amount of attendance can be low in the regular one in some college.

Hey!
they doesn't offer diploma in civil engineering from distance education , they offer B.tech in distance education.
All the best!
