## Homework Statement

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.

## Homework Equations

V = IR so R = V/I

## 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.
