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.
â¦ Some energy is wasted heating the connecting wires because they have some resistance. â¦ The result is a voltage drop along the wire: V = I R and â¦ Joule heating in the wire: Pjoule = I 2 R Both of these effects depend on the current, I, and the resistance, R, but not on the voltage. The connecting wire gets warm from joule heating The bulb filament
