Question

Why potentiometer does not draw current from voltage source?

Answer 1

Explanation:

It is because the voltmeter draws a small amount of current from the voltage source of the circuit connected. So the value shown in the voltmeter may not be accurate. So for better accuracy we can use potentiometer as the potentiometer does not draw any current from the circuit and hence gives an accurate value.
