Does internal linking also pass the juice from one page to other?Should we give a no follow link?
No no, internal linking is very good, you can take Wikipedia for inspiration, you don't need to give them 'nofollow' bro, they are a part of your own website, so no issues.
Yes it will pass..Always give Dofollow only.
Internal linking is too good never do nofollow
Yes, it passes the link juice and for internal linking it should always be dofollow.
