9. A silver block (resistivity at 20°C of 1.59x10-8 Qm) is hooked t a power supply (not in the picture, but it's hooked in where the gap is in the wire.) The current through the block is shown by the arrows. a. Draw the power supply in the gap in the wire. Be sure the direction is correct to produce the direction of current shown. b. Pretend the connecting wires have no resistance. (It's like a frictionless surface!) If 6.1x1023 electrons go through the block every hour, what is the voltage of the power supply? [6.9 µV] 44 cm 13 cm c. Could you attach the wires to different sides to decrease the resistance? Explain how, or why not. d. Could you attach the wires to different sides to increase the resistance? Explain how, or why not. 21 cm
