    You need to learn how to check your own work -- once you get out in the "real world" you will seldom have anyone to do it for you.

    So you have an answer and want to determine if it is correct. Just turn the problem around and start with your answer and imagine that you were given that as the starting point and asked to find the current, whether it was leading or lagging, and what the real power being delivered by the source was. If those answers turn out to be 5A, leading, and 400 W then you can have good confidence that your answers are correct.
