About 2/3 of the population speak German; French is spoken in the west of the country, while Italian is spoken in the canton of Ticino and Romansh in parts of GraubÃ¼nden. The capital of Switzerland is Bern. The largest city of Switzerland is ZÃ¼rich. To the north of Switzerland is Germany.
insulating board so that the entire portion is approximately 4 inches long. The nichrome wire produces heat rapidly with an electric current due to the high level of electrical resistance that the twisted wire holds. This preview has intentionally blurred sections.
The mathematical formula for the Joule heating in a wire is: $$P=V\cdot I=I^{2}\cdot R=\frac{V^{2}}{R}$$. As you can see when a large amount of current passes through a wire then it will get very hot as it is in the second power, obviously with R a constant as you have a specific wire. But if you change the resistance (meaning that you take another wire) using a standard voltage, then using Ohm's Law: $$V=I\cdot R$$. the current I that passes through it must fall, as to continue satisfy the Law.
