Questions & Step-by-Step Solutions
In a potentiometer setup, if the wire is made of a material with higher resistivity, what will be the effect on the measurement?
Correct Answer: Measurement accuracy will decrease.
Step 1: Understand what a potentiometer is. It is a device used to measure voltage by comparing it to a known voltage.
Step 2: Know that the wire in a potentiometer has resistance, which can affect the measurements.
Step 3: Learn about resistivity. It is a property of the material that determines how much it resists the flow of electric current.
Step 4: Realize that if the wire is made of a material with higher resistivity, it will have higher resistance.
Step 5: Understand that higher resistance in the wire means that more voltage will be dropped along the length of the wire.
Step 6: Recognize that this voltage drop can lead to inaccurate measurements because the voltage you are trying to measure may not be the same as the voltage at the end of the wire.
