a) Consider a piece of conducting wire that has a length of 2 cm, a cross-sectional area of 0.2 cm2, and resistance of 1 Ω i. Calculate the electric field inside the wire if the current flowing through it is 2 A ii. Calculate the drift speed of the charge carriers in the wire, if the carrier charge density of the naterial is 1.3E10 C/m3 Calculate the amount of energy transferred into internal thermal energy due to charge carrier collisions with atoms in the material during 1 second. iii. b) Consider a circuit constructed using segments of the same type of wire as above, arranged in the following way, where L 2 cm 2L Calculate Req of the circuit ii. If the emf of the circuit is 12 V, calculate the potential at each of the points a through f. You may assume that this is an ideal emf device, and that the negative terminal of the emf is at zero potential. iii. Which of the following wire segments has the highest power dissipated across it: ab, bf, bc, or de?
