No, because you have to do your own homework to learn.

ok have moved this thread to the appropriate forum section

Hi Dead Civic
welcome to the forums

do you know Ohms Law ? That is the arrangement of V I and R in the triangle ?
if so use that to solve the current flow in the first question

OK so V = I x R

now rearrange that so you can find out what I will equal

remember the triangle V is at the top with I and R below

with that in mind cover the one you are trying to find and see the relationship of the other two

as a hint cover V at the top and you are left with I x R on the bottom
so what happens if you cover I ?

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.
