In every job, there is always these people who can be a fault-finder or power tripper. Are they the same in doing their acts towards others?
No, they are not the same. A fault-finder focuses on finding fault with and criticizing others, while a power-tripper is someone who uses their power and authority over others to get what they want. Both of these behaviors can be destructive, but the power tripper is generally considered more dangerous because they can use their authority in an abusive or oppressive way.
