The part of the resistance wire is cut quickly, while the thicker part is cut. Why?
Oh, I won't. This involves professional knowledge. It's hard to answer. I can't mess with it
so the fine local resistance due to the heat generated, so cutting fast, according to thermal power is equal to I2R the same current, the greater the power resistance is hot
The size of resistance is determined by the material and cross-sectional area, according to your situation is the same material under the cross sectional area of small resistance, current with an electric saw any place is equal,
