Question

OHM's LAW

Of your V vs I plots, were any of them linear? (yes or no)

R_1B __yes___                                             R_S __yes___

   R_2B __yes___                                             R_P __yes___

R_3B __yes__

What might it mean if your plots ARE linear? What might it mean if your plots ARE NOT linear? Explain with respect to Ohm’s Law.

Answer 1

What might it mean if your plots ARE linear? What might it mean if your plots ARE NOT linear? Explain with respect to Ohm’s Law.

If the plots between I and V are linear, then we can say that voltage is directly proportional to current with Resistance , R as the constant of proportionality. This means the object ( conductor) was an OHMIC conductor.

________

If the plots are not linear but are somewhat like parabolic then the conductor is NON - OHMIC. These are conductors for which resistance changes as their temperature changes.
