The hot wire ina toaster disappates
WebThe resistance and current of a toaster The hot wire in a toaster dissipates 580 W when plugged into a 120 V outlet. a. What is the wire’s resistance? b. What are the rms and peak currents through the wire? PREPARE We’ve seen that the 120 V outlet voltage is an rms … WebOn older toasters and older outlets, the power plug can be inserted into the power outlet in one of two ways: one where the hot wire leads to the switch (as shown above) and one where the hot wire is connected to the resistance wire. In this configuration, the resistance wire is at 120VAC even when the toaster is off.

WebWhile in a toaster the element that increases its temperature is usually the nichrome wire that is wrapped around the mica board, while the mica board usually remains at colder temperatures, in my case I'm supposed to consider the heating element as big as the mica sheet, so the heating element is a rettangular shaped element which gets evenly ...
WebA heating element is made by maintaining a potential difference of 75.0 V across the length of a Nichrome wire that has a 2.60×10 −6m 2 cross-section. Nichrome has a resistivity of 5.00×10 −7Ω.m. (a) If the element dissipates 5000 W, what is its length? (b) If 100 V is used to obtain the same dissipation rate, what should the length be?
