## Homework Statement

Say we have a circuit where a cell with internal resistance r is connected to a voltmeter with extremely high resistance. This means practically all of the p.d would be across the voltmeter as the ratio of its resistance to the internal resistance is, say, infinitely high.

So the

**voltmeter reading equals emf of cell**?

Is this reasoning correct?

Thanks!
