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 Nichrome heating element that has resistance 28.0 Ω is connected to a battery that has emf 86.0 V and internal resistance 1.6 Ω . An aluminum cup with mass 0.130 kg contains 0.200 kg of water. The heating element is placed in the water and the electrical energy dissipated in the resistance of the heating element all goes into the cup and water. The element itself has very small mass. How much time does it take for the temperature...
