Immaterial for an electric fuse wire
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. WitrynaIts length is immaterial for an electric fuse fuse is used to avoid danger due to high current if high current is passed through the fuse it burns and disconnect the …

Current flowing through the wire. … Witryna8 lis 2024 · An electrical fuse protects an electrical circuit against damage caused by overcurrent in electronics and electrical engineering. The primary component of the device is a strip or metal wire that melts when too much current moves through it, stopping or interrupting the current. A fuse is a sacrificed device; once it blows, the …
Witryna6 wrz 2014 · Komal Jain, Meritnation Expert added an answer, on 8/9/14. If a fuse wire is connected in parallel of an appliance then it is immaterial for the fuse wire as the current flows through the appliance directly in both cases whether the fuse wire is present or not. This may lead to the damage of the appliance if there is very abrupt … 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.
Witryna13 cze 2024 · If a fuse wire of length l, cross sectional radius r, density ρ is heated due to passage of a current i through it then its equilibrium temperature is one when rate of heat produced in it due to Joule heating is equal to the rate at which heat is radiated to its surrounding which is given as ⇒ ⇒ i 2 R = σ (2 π r l) (T 4 − T s 4 ) i 2 ... Witryna12 kwi 2024 · Vipul Singh. Tutor. 07/02/2024. A fuse consists of a metal strip or wire fuse element, of small cross-section compared to the circuit conductors, mounted between a pair of electrical terminals, and (usually) enclosed by a non-combustible housing. Commonly used material are copper, zinc, aluminium.
WitrynaFuse: A safety device that shields electrical circuits from the consequences of high currents in electrical engineering. There are two types of fuse AC fuse and DC fuse. A lead and tin alloy with a low melting point is used to make fuse wire. Final Answer: Fuse wire is generally made up of alloys of lead and tin.
