Here is the question, for reference:(adsbygoogle = window.adsbygoogle || []).push({});

I have two equations but am having trouble solving them for V, clearly by eliminating I A voltmeter with resistance R_V is connected across the terminals of a battery of emf E and internal resistance r. Find the potential difference Vmeter measured by the voltmeter.

Express your answer in terms of R_V, r, and E.

E-(I*r)-(I*R_V)=0

V_ab=E-(I*R)

Any help would be appreciated, thanks.
