Question

what is the resistance of an ideal voltmeter?

Answer 1

THE IDEAL INTERNAL RESISTANCE OF VOLTAMETER IS INFINITY.....
THE IDEAL RESISTANCE OF AMMETER IS ZERO

Answer 2

Heya.....✋✌

Ideal voltmeter⤵

An ideal voltmeter is a voltmeter, whose reading is accurate. For this, the resistance of the resistor must be very high(tends to infinity).
As such a case is not possible, hence ideal voltmeter is not realistic.
So, for accurate reading of potential difference across any two points in a circuit, we use potentiometer rather than a voltmeter.
Note=>Voltmeter draws current from a circuit while a potentiometer don't.

Hope it helps✅
