Private Placement vs Public Issue: Company Law mein dono kya hain?

Abhi company law mein sabse confused hoon main private placement vs public issue mein. Dono mein isliye confusion hai kyunki private placement public company ke liye hai, lekin private issue public mein hoti hai. Aisa lagta hai ki dono hi ek hi chiz hai, lekin mujhe pata hai ki nhi. Private placement mein public ke sath investment karna hai, jahan public ko share milte hain, lekin yeh nhi ke private company ke share public ko bheje jaate hain. Isme public ko investment ki jaati hai, lekin private company ke share wahi log le sakte hain jinhone investment diya hai.
