    Finding pd given r, R, and emf?

    I finally got! I didn't see the comment you made about the mistake in my simplifying! Thanks for the help

    Finding pd given r, R, and emf?

    I tried out both ways, and each answer was deemed incorrect. 8.385139229 and 8.187569615

    Finding pd given r, R, and emf?

    so, I=7.99/22.445 I=0.355598 then, V=(0.355598)(23) ? or V=(0.355598)(23.555) I don't understand why I'm not supposed to use the total resistance as opposed to just the external resistance.
