Immaterial for an electric fuse wire

Witryna12 maj 2024 · ANSWER. 8. Two electric bulbs have tungsten filament of the same length. If one of them gives 60 W and the other 100 W, then, (i) 100 W bulb has thicker filament. (ii) 60 W bulb has thicker filament. (iii) both filaments are of the same thickness. (iv) information insufficient. ANSWER. WitrynaAn electric fuse is a safety device that protects electrical circuits from excessive current. If a large amount of current passes through the fuse wire, it melts and thus breaks down the circuit. The thickness of the fuse helps in deciding how much current can be passed through the fuse wire before it melts.

Fuse Wire - What is it, What is it made of, Properties

WitrynaA fuse wire is required to blow off at a given current strength say i. Heat Produced ρ = i 2 Rt = i 2 ρl A t. Now, θ ρ msθ = i 2 ρl A t. θ ρ ρ θ = i 2 ρlt Ams = i 2 ρlt A ( lAd) s. or θ ρ θ = i 2 ρt A 2 ds. So, rise in temperature is independent of length.
