1. The problem statement, all variables and given/known data
I'm trying to find the internal resistance of a Voltmeter. The current is 0.212 mA which is measured by I. Rx is 7000 Ohms and the emf of the battery is 1.50 V. 2. Relevant equations V = IR so R = V/I 3. The attempt at a solution How can I start it off to find the Voltmeter's resistance? I don't know exactly to accomplish this. Any help would be appreciated.

Hi thiefjack! Can you provide the full question? I think you have extracted just part of it for this post. This circuit diagram won't get you anywhere.
Or maybe this circuit is your attempt at an answer? What information would you need in order to determine the voltmeter's resistance?
