  1. I have a primary and a child domain for it.
    I want to know whats the use/advantage of having a child domain. I read that it helps in minimize the overloading of primary dc?

    Uhm.. This is AD stuff not some school assignment that you are too lazy to do yourself, is it? WTF did you create a child domain if you have no idea what it is good for?

    There's a basic principle that applies to many facets of life and technology
    Divide and Conquer (also called delegation ) ​
    A Domain Controller has much to do, eg login validation, (frequently) Exchange Server,
    DNS and DHCP services. Creating sub-domains is a means to offload some work to
    other systems (typically situated more closely to the work), so as to free up network and D.C. resources.

    One more doubt regarding this.

    Instead of creating a subdomain can i have an additional DC for the same domain and manage the work load.

    DC workload is a non-issue. Any PC made in this century is able to service thousands of users and any new machine is more than enough for any size of an organisation.
