What might happen if a fuse is not inserted in a household electric circuit?

What might happen if a fuse is not inserted in a household electric circuit?

Answer: If a fuse is not is not inserted in household electric wiring, the fault current flowing in the defective circuit will cause heating and potentially cause a fire before the upstream protection opens the circuit.

What happens if you dont have a fuse?

If you don’t have a fuse everything might burn. At first, Nothing. If a fuse is not installed in the fuse holder, the circuit protected by that fuse is not energized and can not supply electric power. If a fuse is not used in a circuit then there the circuit has no protection.

Why fuses are inserted in household 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.

Where is fuse inserted?

Fuse wire is inserted in live wire because it is a safety device used to protect electrical appliances from short circuit and overloading.

Why is a good fuse wire made of tin?

The fuse wire in a fuse gets melted easily as the value current exceeds the permissible value thus it must be made of a material of high resistance and low melting point. Therefore the fuse wire is made of an alloy of Tin and Lead due to their high resistance and low melting point.

What happens when the fuse blows?

Inside the fuse, there is a metal ribbon through which all the current on the circuit passes. The ribbon is sized to match the circuit wire gauge, and if too much current passes through the ribbon, it melts through, or “blows,” and the circuit goes dead.

What is importance of using fuse and earth wire in household circuits?

(i) A fuse is one of most important protection devices, which is used for avoiding the damages happening due to over load or short circuit. (ii) An earthing wire is used to save us from the risk of electric shock in case the live wire touches the metal case of the electric appliance.

What will happen to the fuse if there is an overflow of electricity?

If a short circuit occurs—or even if too many appliances get hooked up to one wire so that too much current flows—the wire in the fuse heats up quickly and melts, breaking the circuit and preventing a fire from starting.

How fuse is inserted in the wiring?

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 …

Which effect of electricity is used by safety fuse?

Explanation: The heating effect of electric current is also used in the fuse. It is a safety device used to prevent damage to an electric circuit if a very high current suddenly passes through it.

On which effect of electricity does the fuse work?

Heating Effect of Electric Current
An electric fuse works on the principle of ‘Heating Effect of Electric Current’. According to the heating effect of electric current, when an electric current is passed through a current carrying conductor, it does not let the current to flow. As a result the charges start accumulating and hence heat is generated.

What happens if a fuse is not installed in the circuit?

If fuses are not installed in the circuit, then there is no safety barrier to stop excessive current to flow in the circuit due to short circuit/overloading/etc. which can not only lead to wrecking the devices connected to the circuit, but also serious fires due to heating.

What is an electric fuse?

An electric fuse is a safety device used to limit the current in an electric circuit. The use of a fuse is to safeguard the electric circuit and the electric appliances connected in the electric circuit from being damaged.

Why is the fuse wire a thin wire?

Usually the fuse wire is a thin wire to be the resistance of the fuse wire is much more than that of the live wire. If excess current continues to flow in an electrical circuit the wiring will become hot with the potential to cause damage to the wiring insulation and maybe set fire to surrounding combustable materials..

Is it safe to install a circuit breaker without a fuse?

It’s never advisable to install household circuitry without a protective device, eg., fuse, mcb. If there is nothing in place of the fuse, it is an open circuit. No electricity will flow. You’ll be fine, but you won’t have electricity.
