Using an ammeter, you determined that the heating element in your hairdryer has 13.5 A of current through it when plugged into your 120 V outlet plug. The heating element is made of coiled nichrome wire with a radius of 0.21mm. (a) What is the resistance of the heating element? (b) How much charge passes through the hair dryer in 10 minutes? How many electrons would this be equivalent to? (c) Given the information above what is the length of the coiled nichrome wire?
