Question

The heating element of an electric dryer is rated at 4.1 kw when connected to a 240-v line.

Answer 1

Thank you for posting your question here. You just provide a situation, I assume 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?

Below are the answers:

1. P = V∙I
I = P/V = 4100 W / 240 V = 17.08 A

2. Ohm's law:
V = R∙I
R = V/I = 240 V / 17.083 A = 14.05 Ω
