Hi, I'm taking a basic electricity course right now and I'm having trouble understanding a formula. The way they have their example makes no sense to me. Can anybody verify that their example is correct and explain a little bit for me? See attached file.

It seems extremely straightforward. What is it exactly that you do not understand?
 
Hi Jon_H, Welcome to Physics Forums.

In future, please format your question using the template provided in the editing window when you begin a new thread.

The example given is correct. Can you be more specific about what in the example is not making sense to you?
 
Sorry guys, It's been a long time since I've done some real math and totally forgot about finding the lowest common denominator, which would give me the 15+10+6/3000. Brain fart...
