Physics - Current Electricity Question with Solution | TestHub

When resistance$R$is connected in parallel with the voltmeter, the effective resistance will decrease.


According to Ohm's law,

$V=IR$

$R=\frac{V}{I}$

Here,$R$decreases and hence$I$increases. As$I$increases, Potentential across ($A$) increases and hence potential across ($V$) decreases.
