The graph of voltage versus current for the nonohmic resistor was not a straight line. Describe what happened to the current as the voltage increased, compared to what happened for the ohmic resistor.

Answer #1

In nonohmic register the current and voltage does not follow straight line. It gives a curve with and increasing gradient.

This is because as the voltage increases, the electron carries more energy so when they collide in conductor they transfer more energy. This makes the atom vibrate more and more and this increase the temperature thus increase the resistance. And cause the shape of graph.

Whether in ohmic resistance the graph between current and voltage is straight line. So current increase when voltage increases.

The graph in (Figure 1) shows the current through a 2.0 ΩΩ resistor as a function of time. Figure 1 of 1The plot shows the current as a function of time. Time is measured from 0 to 10 seconds on the x axis. Current is measured from 0 to 2.5 amperes on the y axis. First the current stays at 0 amperes from the origin until 2 seconds. Then it jumps to 2.5 amperes and remains at this value until...

Consider a long straight rod of radius R carrying a constant current I of uniform current density. The material of the rod has a very small susceptibility, so you can use χm = 0. A straight long rod with radius R and constant current I with uniform current density, it's susceptibility is considered zero, χm = 0. 1)Calculate outside and inside of the rod, the magnetic field. 2)Include both outside and inside.
