    Hi I'm stuck on question 15 on this link.

    https://251cff15a8166ff37f9e29258122...lectricity.pdf

    There are answers on the website too but I still don't get it and my physics exam is on Tuesday please help

    I've got the first part 150V however I cannot figure out how to get 25V for the voltage across each filament.

    Thank you for any help provided I appreciate it.

    Hello there,

    It seems to me, as if you simply need to apply  V = IR to each component. For the resistor,  V_R = (0.50)(300) = 150 V and for the filaments,  V_F = (0.50)(50) = 25 V . May I ask about your method for the first answer? The method that I have described applies to both components and I am wondering why you were able to get one answer but not the other.

    I used V=IR for my first answer, I clearly was over thinking the question thank you for the help

    You're welcome. Perhaps the context of the question led you to believe that there was something else to be observed.
