Although the effect of using a voltmeter on the electrical current is often insignificant due to the voltmeter's large internal resistance (typically about 10 MΩ), in a circuit with resistance of tens of kΩ or higher the effect can be observed.

Is there internal resistance with voltmeter?

Obviously, the higher the voltmeter resistance, the less loading of the circuit under test, and that is why an ideal voltmeter has infinite internal resistance.

Does a voltmeter have low internal resistance?

Voltmeter has high resistance because it measures the voltage difference between two different points, but it should not change the amount of current going through the element between those two points . So, it should have high resistance .
