Consider cylindrical shape rod of silicon with circular cross-section (resistivity of 3345 , the diameter of 2.53 cm and length of 32.7 cm). Consider a voltage of 1.25*103 V is applied. The temperature coefficient of silicon is -0.005 0C-1 (negative because Silicon is a semiconductor).

(a) Find the resistance of this rod at room temperature? (2 points)

(b) Find the electric field inside the silicon rod? (3 points)

(c) Find the energy dissipations in 3 min? (2 points)

(d) If the resistance of the rod is decreased by 32% after 3min of use then find the temperature change? (2 points)

Consider an electron beam of uniform circular cross-section with a diameter of 1 mm. The electrons are accelerated from the cathode to the anode, which are separated by 1 m. The electrons are generated at the cathode and therefore have negligible velocity at this position. The electrons accelerate at a rate of 108 ?/?2 between the cathode and anode. The current density at the anode is 104 ?/?2 . Find the current density as a function of position between the...
