When an ideal voltmeter is connected between the points E and F (fig) the reading of the meter is `V_(0)`. When an ideal ammeter is connected between E and F, readig is `I_(0)`. Find the current I through a resistor R connected between E and F.
[Hint: The circuit behaves like voltage source of `V_(0)` and some resistance r in series]

Correct Answer - `(V_(0)I_(0))/(V_(0)+I_(0)R)`
