The internal resistance of a voltmeter is the same as the internal resistance of an ammeter.
Resistance is a type of opposition force due to which the flow of current is reduced in the material or wire. Resistance is the enemy of the flow of current.
The ammeter has a low resistance. As a result, the circuit's whole current will travel through it. The internal resistance of the voltmeter,
On the other hand, is very low, thus the current from the circuit does not interfere with the voltmeter's measurement.
Because a perfect ammeter should enable current to travel through it, its internal resistance will be zero. The ammeter is used to measure the current flow across a circuit when it is linked in series.
Because no current should pass through the voltmeter, the internal resistance of the ideal voltmeter is infinite. The potential difference is measured using a voltmeter, which is linked in parallel.
Hence the internal resistance of a voltmeter is the same as the internal resistance of an ammeter.
