What effects of electric current is involved in the fuse breaking?
Applications of the heating effect of electric current include appliances like electric immersion water heater, electric iron box, etc. An electric fuse is an example for the application of heating effect of electric current.

flow of electrons is not visible.only it can be sensed Answer Current can only be detected through one or more of its effects. There are three effects of an electric current: heating effect, magnetic effect, and chemical effect. We use the magnetic effect (the force between currents in parallel conductors due to their magnetic effects) to define the ampere.
An electric current has three 'effects'. These are (1) heating effect, (2) chemical effect, and (3) magnetic effect. Any one of these effects can be used to define the unit of measurement for electric current, the ampere. Until around 1947, for example, the 'chemical effect' was used -i.e. the ampere was based on the mass of silver deposited on an electrode during electrolysis. Since then, the 'magnetic effect' has been used -i.e. the ampere is…
An electric current produces a combination of three effects. These are the heating effect, the chemical effect, and the magnetic effect. The unit of measurement of current, the ampere (A), cold be defined in terms of any of these three effects. However, in SI, the ampere is defined in terms of its magnetic effect -i.e. the force of attraction or repulsion created by the magnetic fields surrounding two, parallel, current-carrying conductors. Prior to its present…
Death, injury, and electricution If we ignore the above, humourous(!), attempt at an answer, then the three effects of an electric current are (1) heating effect, (2) chemical effect, and (3) magnetic effect. Examples of the heating effect include electric heaters, kettles, stoves, etc. An examples of the chemical effect is electroplating. Examples of the magnetic effect includes relays, motors, etc. The SI unit of current, the ampere, is defined in terms of the force…
In electrical engineering, a safety device that protects electric circuits from the effects of excessive electric currents. A fuse commonly consists of a current-conducting strip or wire of easily fusible metal; whenever the circuit is made to carry a current larger than that for which it is intended, the strip melts to interrupt it.
The difference is that "electric current" is a strictly defined, universally interpreted quantity, with a known method of measurement and a rigorously defined unit, whereas "electricity" is a slippery, rubber word, without any scientific definition, or method or unit of measurement, being the popular word used to mean any of the things, effects, or stuff related to electric charge and its motion.
Heat within the wire due to the movement of electrons. A magnetic field around the wire due to the movement of charged particles. Answer There are three 'effects' of an electric current. These are: heating effect chemical effect magnetic effect Since 1948, the magnetic effect has been used to define the unit of current, the ampere -i.e. the ampere is defined in terms of the force between two, parallel, current-carrying conductors.
It doesn't necessarily have a 'function'; it is simply the natural consequence of applying a potential difference across a conductor. However, this is usually done for a reason, and its function is then derived from one or other of the three effects of that current: heating effect -e.g. electric heaters magnetic effect -e.g. electric motors chemical effect -e.g. electrolysis (electroplating)
1. induces magentic field around the conductor. 2.Generates heat in the conductor. 3. Causes shock if flows through human body. Answer The three 'effects' of an electric current are its heating effect, its magnetic effect, and its chemical effect. It's magnetic effect (resulting in the force between parallel conductors) is used to define the ampere.
Direct current is supplied by a nine volt battery. Depends on what you connect to it. If it is a resistor (R) you will get a current of 9/R amps. If capacitors and/or inductors are involved you will get various transient effects depending on what circuitry you use. A short circuit will give many amps for a very short period.
Yes. If strong enough, the electric current can cause intense muscle contractions. The muscle contractions can fatigue the muscle, depleting it of nutrients and electrolytes. When that happens, the muscle is incapable of functioning, and if the muscle happens to be your heart, you die. CPR can be helpful because it brings nutrients back to the heart muscle and provides sufficient blood flow to keep the individual alive until the heart can start again. In…
If you plug an electric toaster rated at 110-v into a 220-v outlet what will the outlet current in the toaster be?
It doesnt matter you will smoke it. The current in a resistive circuit is proportional to the voltage. If the voltage doubles and the resistance is the same (elements) the current will double and burn up both the elements and the toaster wiring. Look up "ohms law" for current voltage and resistance effects. Don't try it..
A current passing through a wire creates a magnetic field around the wire, due to effects of special relativity (the electrons are moving FAST). Alternatively, a changing magnetic field (such as created by a moving magnet) induces electric current in a nearby wire. Faraday's Law describes this behavior.
