What would happen if there is no fuse in the circuit in your home
If there is a fusholder, but no fuse within it, then the circuit is incomplete and no current will flow.
The circuit is ‘dead’If the circuit has been built without a fuseholder, then it will be live and will work normally but without any protection from an overload or a defect..
What is fuse wire used for
The material used for making fuse element has a low melting point such as tin, lead, or zinc. A low melting point is, however, available with a high specific resistance metal shown in the table below. The material mainly used for fuse element are tin, lead, silver, copper, zinc, aluminum, and an alloy of lead and tin.
Is a fuse wire always connected in parallel with the main line
Fuse wire is always connected in series. … Assertion: A fuse wire is always connected in SERIES with the mainline. Reason: If a current larger than the specified value flows through the circuit, fuse wire. melts AND OPENS THE CIRCUIT SO THAT CURRENT CAN NOT PASS THROUGH CIRCUIT ANYMORE.
Is a fuse connected in series or parallel
A fuse is nothing more than a short length of wire designed to melt and separate in the event of excessive current. Fuses are always connected in series with the component(s) to be protected from overcurrent, so that when the fuse blows (opens) it will open the entire circuit and stop current through the component(s).
What Colour wire is connected to the fuse in a plug
In a plug, the blue neutral wire goes to the left, the brown live wire to the right and the green and yellow striped earth wire to the top. The fuse fits next to the live wire.
What will happen if fuse is connected to neutral wire
The answer is simple. The current flows in excess, but the circuit doesn’t disconnect. The same may happen if the fuse is connected to neutral. Because the fuse can disconnect the circuit only when the excess current flows completely through the neutral.
Can I use 3 amp fuse instead of 5 amp
If you replace it with a 5A fuse you will lose part of the protection the 3A fuse was intended to provide. In case of a failure of the device the fuse is suppose to protect, the result of using a larger fuse could be to damage the device to the extent that it could not be repaired. It could also start a fire.
What happens if you don’t use a fuse
If there is a fuse and an overcorrect occurs, the fuse will melt and stop the floor of current, hence protecting the device. In the absence of the fuse, the device will experience an over current and it will be damaged.
Why fuse is not connected in parallel
A fuse connected in one branch of a parallel circuit, of course, would not affect current through any of the other branches. … Having no fuse could result in destroying the equipment and/or a fire.
Where is fuse wire connected
A fuse wire is always connected to the live wire so that if excessive current flows through the live wire, then fuse wire melts itself and prevents the appliance from damage.
What fuse to use
For an appliance rated as 700W or less, a 3A fuse should be fitted. For appliances above 700W, a 13A fuse should be fitted. One complication of using the 700W rule is that some appliances can draw a higher current when they are first switched on (inrush current).
Why is electrical fuse needed
A fuse(s) is needed in any electrical system (AC or DC). These protection devices react to the amount of heat being produced by electricity passing through wires and/or components. They are used so as to protect wires and components from the extreme heat produced should there be an electrical overload or short circuit.
Why is it dangerous to put a fuse in the neutral wire
So, whenever the current flow through the fuse rise beyond its limit, the fuse will burn out and opens the circuit. The answer is simple. … The same may happen if the fuse is connected to neutral. Because the fuse can disconnect the circuit only when the excess current flows completely through the neutral.
Where do we connect fuse with live wire or with neutral wire
Fuse is always connected to live wire. If fuse wire is connected to neutral wire instead of live wire then even when the fuse burns out, the appliance remains connected to the live wire and the current supply will not be disrupted due to over loading.
How do you know if a plug fuse is blown
Look at the fuse wire. If there is a visible gap in the wire or a dark or metallic smear inside the glass then the fuse is blown and needs to be replaced.
What happens if there is no fuse
If there is a fusholder, but no fuse within it, then the circuit is incomplete and no current will flow. The circuit is ‘dead’If the circuit has been built without a fuseholder, then it will be live and will work normally but without any protection from an overload or a defect.
What happens when you remove a fuse
If you removed a fuse or breaker for the ignition or fuel injection systems, the car wouldn’t start (assuming it’s a gasoline-powered vehicle). But, in a broader sense, you won’t harm the vehicle by removing fuses and leaving them out.
Is the earth wire connected to the fuse
However, the earth terminal is connected to the metal casing so that the current goes through the earth wire instead of causing an electric shock. A strong current surges through the earth wire because it has a very low resistance . This breaks the fuse and disconnects the appliance.
Why is fuse connected to live wire
The fuse wire is always connected in the live wire of the circuit because if the fuse is put in the neutral wire, then due to excessive flow of current when the fuse burns, current stops flowing in the circuit, but the appliance remains connected to the high potential point of the supply through the live wire.
