(a) A ceiling fan has 91 Ohms of resistance. Suppose 340 meters of copper wire were added to the circuit to carry current from the fuse box of your house to a celling fan on the necond floor. The wire has a diameter of 0.00054 m, and the potential difference across the wire and fan is 120 Volts. Determine the amount of current passing through the circuit. The resistivity of copper is 1.7e-08 ohm-meters. MngMeters ef ire Feuer Supple (b) If the diameter of the copper wire was reduced by one-half, by what factor would the resistance of the wire change? Describe how you figured this out. Please explain fully
