The resistivity of gold at room temperature is 2.35 x 10-8 ohm-m. The temperature coefficient alpha = 3.98 x 10-3/K. What will be the resistivity of a piece of gold whose temperature is 150°C above room temperature?
The resistance of the tungsten filament of an
incandescent light bulb at 22 degC is 34 Ohms. If the
light bulb is connected to a voltage of 126 V a current
of 0.36 A flows through the filament. What will be the
temperature of the light bulb filament under working
conditions? The temperature coefficient of resistance
of tungsten is 4.6E-3 1/degC. Your answer must be in
degC, other scales are not accepted.

4. Maximum surface resistance. Consider a square sheet of side L, thickness d, and
electrical resistivity p. The resistance measured between opposite edges of the sheet
is called the surface resistance: R = pL/ Ld = p/d, which is independent of the
area of the sheet. (R is called the resistance per square and is expected in ohms
per square, because p/d has the dimensions of ohms.) If we express p by
p=m/ne²t, then Rq=m/ndet. Suppose now that the minimum value of the
collision time is determined by scattering from surfaces of the sheet, so that
