The heating element of a clothes dryer has a resistance of 18 . A voltage of 220 V is connected across the heating element. What is the current in the heating element?
R = 18 Ω
V = 220 V
Let the current be I.
We know,
V = I * R
I = V/R
I = 220/18
I = 12.22 A

Heading 2 Title Sut 18) The heating element in an iron has a resistance of 24 22. The iron is plugged into a 120 V outlet. a) What is the power dissipated by the iron? 19) Given a timing circuit, you are asked to connect the following components in series. A 4mH and a 200 22. They car connected with a 30 V voltage source that has angular frequency of 250 rad/s. e) What is the impedance of the entire...
The heating element in a hair dryer is essentially a wire whose resistance causes it to become red-hot when a current exisits in it. Such wires are usually made of nichrome (a nickel-chromium alloy), whose resistivity is p=1.0*10^-6 ohm*m. (a) Suppose one such wire has a diameter of 0.30 mm and a resistance of 9.0 ohm. What is the length of the wire? (Note that wires like this in a hair dyrer tend to be coiled around to save space)...

A clothes dryer runs on 4000 W. If the dryer draws 11 A of current, what is the resistance of the dryer?
A certain toaster has a heating element made of Nichrome resistance wire. When the toaster is first connected to a 140-V source of potential difference and the wire is at a temperature of 20.0°C), the initial current is 1.70 A, but the current begins to decrease as the resistive element warms up. When the toaster reaches its final operating temperature, the current has dropped to 1.53 A. (a) Find the power the toaster converts when it is at its operating...
