What do you think will happen if a thick wire is used as a fuse?

What do you think will happen if a thick copper wire is used as a fuse?The resistance of a conductor is proportional to its length and inverse proportional to its cross-sectional area. So, If the fuse wires are thick, the larger cross section decreases the resistance across the fuse wire. So, even a high current flows through the fuse, it doesn't blow out.

Can a copper wire be used as a fuse explain? Solution: No, we cannot use copper wire as fuse wire because the melting point of copper is higher and resistance is low and hence, current can flow through it without melting it or breaking the circuit and it can't be limited.

Which thick thin wire is used for fuse?

A fuse is a thin wire made of a material like tin or tin-lead alloy having low melting point which melts and breaks off the circuit if the current exceeds the safety limit.

What is the advantage and disadvantage of using a thick fuse wire?

The resistance is inversely proportional to the cross-section of the wires used, so thick wires mean low resistances. So, even if high current flows through the fuse, it will not melt thus causing damage to electrical devices during faults. This is the disadvantage of using thick fuse wires.

What happens if fuse wire is thick?

The resistance of a conductor is proportional to its length and inverse proportional to its cross-sectional area. So, If the fuse wires are thick, the larger cross section decreases the resistance across the fuse wire. So, even a high current flows through the fuse, it doesn't blow out.

Can I use normal wire as fuse wire?

So, owing to the above reasons, it is not advisable to use copper wire as fuse wire, since there won't be any difference between normal wire and fuse wire. It is very much advisable to use alloys in place of pure metals that have low melting point.

What is the main advantage of using fuse?

Cheapest type of protection. Current limiting effect under short circuit conditions.

Why cant we use a copper wire as a fuse wire Brainly?

Copper wire is not used as a fuse wire because pure copper has a high melting point and will not melt on a slight increase in current.

Are fuses made of copper?

A pure copper wire can not be used as a fuse wire because it has a high melting point due to which it will not melt easily when a short circuit occurs. Usually a short length of a thin, tin plated copper wire having low melting point is used in a fuse. A fuse is connected in series in domestic electric circuit.

Why is a thin wire used in electric fuse?

Because it just acts as a normal electric contact in the circuit or wiring. In order to reduce the area and to maintain a minimum resistance to generate heat, fuses are made as thin. A fuse wire should not have high resistance or low resistance.

Can we use a thick wire as a fuse wire explain?

Expert-verified answer
no, in a fuse wire a thin wire is used instead of a thick wire because if the current increases then the fuse wire melts thus cutting off the supply. and further protecting the circuit.

What is a disadvantage of using fuses?

It is not suitable for overload, at that time fuse blow off replacing of fuse takes time. During this period of lost power. The protection of fuse is not reliable.

Can a copper wire be used as a fuse wire?

Copper wire cannot be used as a fuse wire since melting point of Cu is higher and resistance is very low and current can flow through it without melting it and without breaking the circuit resulting in appliance damage .

What is electric fuse what are its advantages?

It is switchgear protection equipment that we use daily even at our house. Fuse is a protector and safety device for power circuits. It helps to protect from fault conditions such as short circuits, overload, damaged equipment, or mismatched load conditions.

What are two advantages of using a fuse over a circuit breaker?

Fuses are initially less expensive than circuit breakers. Fuses have a smaller footprint in a control cabinet. There are a variety of fuse types for different applications. Fuses can be more reliable over time, because they do not have moving parts.

Why we Cannot use a copper wire as a fuse wire?

Copper has a higher melting point than the tin used in fuse wire. So, when a high level of current runs through copper wire, it continues to heat but will not melt. Instead, it causes a short circuit – potentially ruining your appliance and sparking a fire.

Why a pure copper wire Cannot be used as a fuse wire?

Copper wire cannot be used as a fuse wire since melting point of Cu is higher and resistance is very low and current can flow through it without melting it and without breaking the circuit resulting in appliance damage .

What material are fuses made of?

The fuse element is made of zinc, copper, silver, aluminum, or alloys among these or other various metals to provide stable and predictable characteristics. The fuse ideally would carry its rated current indefinitely, and melt quickly on a small excess.

What is fuse made up of?

Fuse is generally made up of an alloy of tin and lead. It is used in series with an appliance to prevent it from damage when excessive flows through the appliance. Material to be used in fuse wire must have Low melting point, low boiling point and high electric resistance.

What will happen if a thick copper wire is used as a fuse?

Copper has a higher melting point than the tin used in fuse wire. So, when a high level of current runs through copper wire, it continues to heat but will not melt. Instead, it causes a short circuit – potentially ruining your appliance and sparking a fire.

What are the advantages and disadvantages of Rewirable fuse?

The rewirable fuse has the advantages of replacement of fuse element without any risk. The cost of the replacement is also very less. The following are the disadvantages of the rewirable fuse. Unreliable Operation – For the working of the fuse it is essential to choose the element of suitable size.

Can you use any metallic wire as a fuse wire?

Yes, we can utilize any other metals like aluminium, lead, silver, copper, and tin as fuse wire. Explanation: As Tungsten has a highest melting point of almost 7000 degrees Fahrenheit which makes it useful for fuse wires and light-bulb filaments.

What is electric fuse short answer?

An electrical fuse is a safety device that operates to provide protection against the overflow of current in an electrical circuit. An important component of an electrical fuse is a metal wire or strip that melts when excess current flows through it.

What do you mean by electric fuse?

In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current.

Why lead is used in fuse?

Generally fuse wire is made of an alloy of lead and tin because its resistivity is high and melting point is low.
