Thank you for posting your question here. You just provide a situation, I guess below are the questions:1. What is the current in the heating element? 2.What is the resistance of the dryer's heating element at its operating temperature?The following are the answers:1. P = V∙I I = P/V = 4100 W / 240 V = 17.08 2. Ohm's law: V = R∙I R = V/I = 240 V / 17.083 To = 14.05 Ω
