Question

An ammeter and a voltmeter of resistance R are connected in series to an electric cell of negligible internal resistance. Their reading are A and V respectively. If another resistance R is connected in parallel with the voltmeter, then

TestHub · Accepted Answer

The effective resistance will decrease when resistance $R$ is connected in parallel with the voltmeter.
According to Ohm's law, $V = IR$ or, $R = \frac{V}{I}$ Here, as $R$ decreases, so $V$ decrease and $I$ should increase.
