Question

This is Resistance and Resistivity lab questions.

The current should be adjusted by adding more resistors in either series or parallel. turning the fine knob on the power supply setting the appropriate value in Capstone. turning the coarse knob on the power supply The best-fit curve for the area vs. resistance graph is expected to be: an inverse-squared function because the resistance is inversely proportional to the radius squared, an inverse function because the resistance is inversely proportional to the area linear because the resistance is proportional to the area. quadratic because the resistance is proportional to the radius squared. The resistance of a light bulb filament is: constant because it is made of conducting material, is not constant and increase with increasing current, is not constant and decreases with increasing current, is constant because it is ohmic.

Explanation / Answer

1) Option 1 is correct

Adding resistors in circuit either in parallel or in series

because we know Ohm's law V = IR

2) option 2 is correct

because if we increase area, resistance will decreases

3) By Ohms Law, If we increase the current, resistance will decrease so that option 2 is correct.
