Question

What is a voltmeter and resister

Answer 1

Putting a voltmeter across the load to measure the voltage will lower the resistance and cause more current to flow in the circuit. ... The best voltmeter will have such a high resistance that it will not significantly change the current in the circuit. Good, modern voltmeters have several meg ohm input resistance.

Answer 2

a voltmeter is an instrument used for measuring electrical potential difference between two points in an electric circuit.

a resistor is a passive two -terminal electrical component that implements electrical resistance as a circuit element .
