There are three voltmeters of the same range but of resistances

10000\,\,\mathrm{\Omega },\,\,8000\,\,\mathrm{\Omega }

and

4000\,\,\mathrm{\Omega }

respectively. The best voltmeter among these is the one whose resistance is

View answer and explanation

Correct option: A

10000\,\,\mathrm{\Omega }

Option A (

10000 \,\,\mathrm{\Omega }

) is correct because a voltmeter with higher resistance draws less current from the circuit, providing a more accurate reading.
