A=97 B=107 C=207 A= B= 1. a. The figure shows cross sections through three long conductors of the same length and the same material, with square cross sections of edge lengths as shown. Conductor B fits snugly within conductor A, and conductor C fits snugly within conductor B. Rank the cross-sectional areas of A, B, and C? Rank the resistance of A, B, and C? Explain how? (10 points) 2a a/2 b. Two wires, a and b, are made of the same metal and have equal length, but the resistance of wire a is A 2 the resistance of wire b is B 2. How do their diameters compare? (10 points) c. Draw three resistors of A $2, B 2 and C $2 in series to each other and connect them to the battery of 12 V, calculate equivalent resistance and the current? Calculate the voltage and power dissipation across each resistor? If one resistor is burnt, what will be the current of the circuit? (10 points) d. Draw the above three resistors in parallel to each other and connect them to the battery of 12 V, calculate equivalent resistance and the current? Calculate the voltage and power dissipation across each resistor? If one resistor is burnt, what will happen to the current going through the battery? You can burn one of them and discuss the answers. (10 points)
