Why is fuse inserted in an electric circuit?
Hint: A fuse is a device that is used to protect electrical appliances and circuits from damage. … Its work is to detect any kind of short circuit and stop the flow of current from that circuit.
How is a fuse put in an electric circuit?
How is a fuse put in an electric circuit? … The fuse wire is stretched between the two metallic terminals T1 and T2 in a porcelain holder (since porcelain is an insulator of electricity). This holder fits into a porcelain socket having two metallic terminals to which the live wires of the circuit are connected.
How does a fuse work in a circuit?
The fuse breaks the circuit if a fault in an appliance causes too much current to flow. This protects the wiring and the appliance if something goes wrong. The fuse contains a piece of wire that melts easily. If the current going through the fuse is too great, the wire heats up until it melts and breaks the circuit.
What is electric fuse how it is connected with live wire?
The fuse wire is always connected in the live wire of the electric circuit because if the fuse is somehow put in the neutral wire in the circuit, then due to excessive flow of electric current when the fuse burns, current will stop flowing in the circuit, but the appliance will still remain connected to the high …
Is a fuse connected in series or parallel?
Fuses are always connected in series with the circuit to be protected from excessive current. … When the fuse is connected parallel to the circuit would not affect current through any of the other branches.in fuse resistance of the strip will generate heat due to the current flow.
Why fuse wire must always be connected in Live wire explain?
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.
Which is not correct in the case of an electric fuse?
Fuse is designed to limit the maximum current. There is a maximum limit of current above which the fuse blows and the circuit is broken. Option (c) – This is incorrect.
Are wires still live if switch is off?
Even with the switch off, there are live wires at the light. You should be just fine with the light switch turned off. If the light switch is not in close proximity to the socket where you will be working, place a sign over it or tell family members to not touch it.
Do I need a fuse between switch and relay?
Yes, The “main” power to the relay fuse, then to the compressor when you switch to “on” will protect the rely and the compressor “if” fused at the power source or at least before the relay. The reason to protect as close as possible to the power source with a fuse/breaker is just in case you have a short in the wire.
