Homework Statement
When a certain 9.0V battery is connected to a voltmeter, the voltmeter reads 8.00V (assume that the voltmeter has an internal resistance of 10MΩ. We may conclude that
(A) only 1/9 of the battery's fuel has been used, and so the battery has plenty of life left in it.
(B) the battery is nearing the end of its life, but is still usable.
(C) the battery is unable to provide more than a few μA of current to any circuit (even a short circuit), and so is therefore (for all practical purposes) completely dead.
Homework Equations
V = IR
The Attempt at a Solution
No idea honestly. It seems that the battery has plenty of life in it, but that's the wrong answer.
