dead civic, perhaps you can tell us why you need to solve these problems.
Are you the parent of a student or something? It's almost impossible to believe that you could be a student trying to answer the questions because I would expect a glimmer of understanding by this point.
Do you know what a milliamp is compared to an amp?
Do you know what a kiloohm is in relation to an ohm?
Do you know the units used to measure voltage?
Do you know the units used to measure current?
Do you know the units used to measure resistance?
At the very least you need to know the answers to the previous 5 questions before you can even consider attempting this question.
