Why is an electric fuse required in all electrical appliances?

Since the current in series remains the same, the fuse wire gets melted and breaks the circuit thereby protecting the appliance from getting damaged. Hence an electric fuse required in all electrical appliances for the protective reason of the appliance.

Why is an electric fuse required in all appliances?

Answer: a fuse is a device which has low melting point. So when high amount of current passes through it , due to heating effect if electric current, it melts and thus breaks the circuit to prevent the flow of electricity. As a result it prevents short circuit and saves the electrical appliance from damage.

What is the purpose of an electric fuse?

Electric fuse is a safety device used to limit the current in an electric circuit which melts and breaks the circuit whenever there is an excess flow of current through the circuit.

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.

GOOD TO KNOW:  Best answer: Which is the most commonly used semiconductor in making solar cells?

Which Mark is necessary on electric appliances?

ISI mark is the mark necessary for appliance approval.

Why is an electric fuse required in all electrical appliance class 7?

Since the current in series remains the same, the fuse wire gets melted and breaks the circuit thereby protecting the appliance from getting damaged. Hence an electric fuse required in all electrical appliances for the protective reason of the appliance.

What is an electric fuse short answer?

An electric fuse is an electric device which interrupts the flow of current in an electric circuit. It is installed in a circuit to stop the flow of excessive current. A fuse is usually a short piece of wire. … Normally an alloy of tin and lead is used as the fuse wire, as it has high resistivity and low melting point.

Can I put a 5a fuse in a 10a plug?

Possibly yes. It is possible to short out a circuit by overdrawing more than 5 Amp by removing the 5 Amp fuse and putting in a 10 Amp fuse.

How can you tell if a 13A fuse is blown?

Remove the fuse from its holder. In some cases you may need a small screwdriver to unscrew the fuse holder cap. 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.

Is there a fuse in a wall socket?

There is no fuses in a normal plug sockets.
