    I want to know in this circuit if v3-v4 = v4-v5. if it is indeed the case, can someone please tell me how we end up with that expression.

    Write 3 equations, solve V3, V4, V5 and verify for yourself.

    What can you say in general about the current flowing in any series circuit?

    You should solve the circuit if you can, but numerical results may not be possible unless you have some information about the devices used.

    Note that in where the MOSFETS were in all respects identical, you might come to a particular conclusion.


    Edit: OOPS, I have had to delete a comment which would be incorrect for enhancement devices, as these look to be!
