1. What is short circuit? What is the common cause of unintentional short circuits in electrical devices?
-A short circuit (sometimes abbreviated to short or s/c) allows a charge to flow along a different path from the one intended. The electrical opposite of a short circuit is an open circuit, which is infinite resistance between two nodes. It is common to misuse "short circuit" to describe any electrical malfunction, regardless of the actual problem.
-improper usage of any devices
2. What is a fuse? What happens when you blow a fuse?
-is a type of overcurrent protection device. Its essential component is a metal wire or strip that melts when too much current flows. When the metal strip melts, it opens the circuit of which it's a part, and so protects the circuit from excessive current.
-when we are going to blow the fuse, its current temperature will be change and will lead to malfunctioning.
3. How do Circuit breakers Work?
-a circuit breaker is an electrical device which disconnects (By tripping) the circuit in case of fault .... later when the fault is removed it can again be switched onwhere as a fuse will burn out in case of overload and u have to replace it with a new fuse....
-Circuit breakers and fuses work in 2 ways.They will disconnect power if there is a short circuit or if there is too much current running through the device, causing heat to cut the power.
4. When is there an overload in a circuit?
-is a situation where the wiring to or within a machine or system is subjected to a greater electric current load than it was designed to carry, leading to excessive heating of the wires and a possibility of fire. This excessive current load can be a result of electrical insulation failure ( a short circuit) or human error. A correctly designed electrical system incorporates suitable overload protection devices to prevent damage should such a situation occur. Fuses and circuit breakers are most commonly employed for this purpose.
5. Why will too many electrical devices operating at one time often blow a fuse?
-inEquality between the distribution of electric current.
6. What are the dangers of short circuit and overload?
-you will surely risk your life if you were having an improper fuse and overloading••••
it may coZ fires and may also kill your liown life•••
