Why is fuse wire always placed in?

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.

Why is fuse wire always placed in a circuit?

A fuse is a circuit element made of highly resistance material such that melts when there is overloading in the circuit. It is always connected in the live wire as to break the circuit preventing the connected devices from damage.

Where is the fuse wire placed in an electric circuit?

The fuse is placed in the live wire just after the 'electricity meter' of the consumer. Fuse wires are generally made of an alloy of tin and lead and have a relatively low melting point.

Why fuse is not used in neutral?

If it is connected to neutral wire, the fuse will melt when excess current flow, but the appliance will still be connected to high potential through live wire. Thus, if a person touches the appliance, he receives shock.

Why a fuse wire is always connected in parallel with the main line?

Fuse wire is always connected in series to prevent the electrical appliances from damage due to unwanted high current in the circuit.

ICSE, PHYSICS, FUSE WIRE IS CONNECTED IN LIVE WIRE...WHY ??? EASY TO UNDERSTAND EXPLANATION

Why are fuse and switch always fitted in phase wire?

Solution. 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 ...

What is short circuiting class 10th?

Short circuiting: It occurs sometimes that the live and neutral wires come in contact with each other, and this result is called short circuiting. In such instances, the resistance of a circuit decreases to an extremely small value. The decreasing of resistance results into the increase in the current.

What is over loading science?

If more electrical appliances of high power rating like electric iron box, electric cooker, electric heater, air conditioner etc., are switched on at the same time, they draw an extremely large current from the circuit is calledoverloading. Physics.

What is overloading in science?

The current in a circuit depends on the rating of the appliances connected to it. If the total current drawn through a wire by the appliances connected to it exceeds the safety limit for that wire, it gets overheated. This is known as overloading.

What is an electromagnet Class 7?

Answer: An electromagnet is a coil of insulated wire wound around a piece of a magnetic substance such as soft iron. The magnetic substance acts as a magnet as long as the current flows in the wire.

Why fuse is not connected in parallel?

When the fuse blows it will open the entire circuit and interrupt or stop the flow of current through the circuit. 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.

Is fuse connected in series or parallel?

Electric fuses are always connected in series with the live wire.

Are fuses directional?

A: Yes, fuses are directional. Electricity should flow from the left to the right when you view the fuse. If you do not know the direction of flow you should listen to the fuse inserted in both directions.

What is melting point of fuse?

Answer: Solution: Fuse wire is made of alloy of lead and tin having low melting point of 200°C.

Does a fuse have low resistance?

A fuse wire should have high resistance and low melting point. So that it prevents current higher than the prescribed value to pass . Low melting point will let it to break when high current passes through it because of the heat generated.

Can you fuse the neutral?

Watch out: it is unsafe to fuse the neutral wire in addition to or rather than the "hot" wire in an electrical circuit because an over-current may blow the "neutral" fuse while leaving the circuit's hot or feed side wire electrically live.

What is electrical pressure called?

The term to describe pressure in electricity terms is 'voltage'. It's measured in volts using a voltmeter.

What is an electromagnet how a soft iron piece can be transformed an electromagnet?

The insulated copper wire is warpped on a soft iron piece. When current is passed through the coil using a battery and a key the iron piece behaves like a bar magnet as long as current is being passed. Such a magnet is called an electromagnet.

How does school bell work?

When the switch (K) is closed, an electric current passes from the battery (U) through the winding of the electromagnet. It creates a magnetic field that attracts the iron arm of the clapper, pulling it over to give the bell a tap.

What is the purpose of the soft iron core used in making an electromagnet?

The soft iron is used to make the electromagnets because the soft iron has good or high magnetic properties. It can provide a strong magnet.

What is an electromagnet State two uses of electromagnet Class 7?

A magnet that consists of a piece of iron or steel surrounded by a coil is known as an electromagnet. When an electric current is passed through the coil, the metal becomes magnetic. Two uses of electromagnets are as follows : In electrical devices such as in loudspeaker, electric bell, and electric motor.

What is a solenoid class 10?

A solenoid is a coil of wire bound across a corkscrew-shaped piston, usually made of iron. Electromagnets have the advantage over permanent magnetic materials in that they can be switched on and off by changing the electrical field, making them useful as controls and switches that can be automated.

What is electromagnetic induction class 10?

Electromagnetic Induction is a current produced because of voltage production (electromotive force) due to a changing magnetic field. This either happens when a conductor is placed in a moving magnetic field (when using an AC power source) or when a conductor is constantly moving in a stationary magnetic field.

What is a bellringer exam?

What is a bell-ringer exam? A type of lab exam in which a limited amount of time is given at each station, and a bell (or other auditory signal) indicates that you must move from one station to the next. Because of this unique format, it's important to find out all you can about the exam.

What word is school?

noun. an institution where instruction is given, especially to persons under college age: The children are at school.
