1. Nichrome is a metal alloy that is used in resistive heating elements for space heaters. It has a resistivity of p = 106 ohm-m. Consider a nichrome wire that is 20 meters long and of diameter 0.25 mm. Assume that it is placed across a 115-volt power supply like in a typical home. a) Calculate the resistance R of the wire. Be sure to state the unit. b) Calculate the current I through the wire. Be sure to state the unit. c) Calculate the drift speed E of free charges in the wire. Be sure to state the unit
