CALC The region between two concentric conducting spheres with radii and is filled with a conducting material with resistivity . (a) Show that the resistance between the spheres is given by
Why does an electric light bulb nearly always burn out just as you turn on the light, almost never while the light is shining?
A cylindrical rod of diameter is connected to
a power supply that maintains a constant potential difference of across
its ends, while an ammeter measures the current through it. You observe that
at room temperature the ammeter reads while at it
reads . You can ignore any thermal expansion of the rod. Find (a) the
resistivity at and (b) the temperature coefficient of resistivity at for the material of the rod.
