    No, you find V.

    (In other words, show an attempt at a solution, and we'll help. We're here to help with homework, not do it for you.)

    Welcome to PF!

    Hi chronicals! Welcome to PF! :wink:

    Give names i1 i2 etc to the currents through the various parts of the circuit, and then use Kirchhoff's rules …

    show us what you get. :smile:

    Hi chronicals!

    Please always use the forum for homework help, not PMs.

    And no, PF rules are that you have to solve the problem …

    all we do is help.​

    So … give names i1 i2 etc to the currents through the various parts of the circuit, and then use Kirchhoff's rules …

    and show us what you get. :smile:

    Give me concrete directions, what should i do firstly, show me clearly

    You were clearly told to label the currents and apply Kirchoff's rules.

    At least try to put something on paper. If you can't even label i1, i2, et cetera, in each mesh (or loop as my book calls it), then you're in far deeper trouble than we can help with.
