Welcome! We'll be happy to help, but remember that we're not going to do your homework.
Your best chance of getting the help you need is to tell us the question, tell us what you've figured out, and where you're stuck.
If the problem is a more general nature, like "I don't understand Thevenin" (for example) then the best approach is similar. Tell us what you've figured out, and where you are stuck or confused.
Open ended, or vague questions will often be answered with a link to Google or wikipedia.
