Fuse is a circuit element which disconnects the electrical current from the mains"supply"

feeding the load when a condition of fault "short circuit " occurs.

one behaviour of electric current that it flows undivided in circuit elements connected

in series and is divided when flows in circuit elements connected in parallel.

so in order to protect a circuit fuse MUST be connected in series to cut/disconnect the faulty current in a safe/short time.

if u connect a fuse in parallel to a component then u will be shorting that component and

the component will not function ;because the fuse is a thin wire with a negligible resistance

and electrical current flows in the most easy "less resistive" component.

besides a short circuit will happen immediatly because u connectthe supply to the neutral!

hope that helps.

How do you make a combined series and parallel circuit with using fuse also?

To create a combined series and parallel circuit with a fuse, first arrange some components (like resistors) in series, connecting them end-to-end. Then, take one or more of those series components and connect them in parallel with the fuse placed in series with the entire setup to protect the circuit. Ensure the fuse is rated appropriately for the total load of the circuit, providing a safeguard against overcurrent. Finally, connect the power source to the circuit and test it for functionality.


How is the fuse connected in the circuit?

The fuses are held by spring metal clips , the clips are themselves being permanently connected to the circuit conductors.


What are the images of series and parallel circuit?

parallel circuit, a circuit containing two or more subcircuits connected across each other allowing current flow to divide between them, the voltage across all of these subcircuits is identicalseries circuit, a circuit containing two or more subcircuits connected inline with each other allowing the voltage to distribute across them, current flow through all these subcircuits is identicalopen circuit, a circuit with a break (or opening) in it, preventing current from flowingclosed circuit, a circuit with no breaks (its fully closed) in it, permitting current flowshort circuit, a circuit having an unintended low impedance path (or shortcut path) somewhere in it causing current flow to bypass one or more subcircuits within the circuit; this often causes excessive current flow and damage, unless a fuse melts or a circuit breaker pops to create an open circuit and thus protect things

Will a fuse work successfully connected in parallel?

Absolutely not. A fuse works by "monitoring" the current flowing in the circuit. Setting the fuse next to whatever it should be monitoring will do absolutely no good.

Should a fuse be in a series or a parallel circuit with the main power coming into a house?

i think a fuse should be in a parallel circuit with the main power because if something from your house turns off you can go look in the fuse box instead of every single one being alone that's what i think(p.s who's is better mine or the one that just said series's)


Why is the fuse always connected in the beginning of the circuit?

A fuse is an over current protection device, and will operate wherever it is placed in a circuit. However, because it's important that it isolates the faulty circuit from the supply, it MUST be located in the line (NEVER the neutral) conductor at the point where the circuit is connected to the supply.The point is that the circuit will always be energised (and potentially dangerous) up to the point where the fuse is connected, even when the fuse has operated and no current can flow.


Predict whether a fuse will work successfully if it is connected in parallel with the device it is supposed to protect?

A fuse will not work successfully if it is connected in parallel with the device it is supposed to protect.First, it will blow because it has no resistance in series with it. Second, once it blows, the device still has power applied to it. Fuses must be wired in series.

Will a fuse work successfully if it is connected in parallel with the device it's supposed to protect?

No, a fuse will not work successfully if it is connected in parallel with the device it is supposed to protect. Fuses are designed to be connected in series with the device, allowing them to interrupt the current flow when an overcurrent condition occurs. If connected in parallel, the fuse would not experience the same current as the device, and it would not protect it effectively from overcurrent situations.
