Name Any two effects of electric current?
Electromagnetism and ( through a proper resistant material ) Heat.
Effects of an Electric current - 1) Heating effect - e.g. - Heater / Geyser etc. 2) Magnetic effect - e.g. - Electric Bell etc. 3) Chemical effect - e.g. - Battery charging etc. 4) Lighting effect - e.g. - Electric bulb etc.
Toaster, oven, toaster oven, flat iron, curling iron, electric clothes dryer, hair dryer, soldering iron, heat gun, arc welder, windshield defrosters, roof deicers
Yes. Any electric current is surrounded by a magnetic field.
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.
Yes. That is what is causing the current to flow through the resistance of the conductor
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… Read More
the rate of flow of electric charge through any cross sectional area is called electric current. by,Rameen Riaz
Any time there is ANY flow of electric charges (any current), the current will be surrounded by a magnetic field.
You can't detect the presence of electric current in a conductor with any human sense.
Just like any other quantity in algebraic expressions, equations, and formulas, electric current can be represented by any letter or symbol with which you're comfortable. Out of tradition and force of habit, electric current is most often represented by "I" or "i". But there's no great reason why it has to be.
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… Read More
It might be possible to characterize an electric charge as a current -- if that charge is moving. Any moving charge is electricity under the fundamental definition of that term. Electricity is generally thought of as moving electrons, but a more fundamental definition of electricity is any moving charge or group of charges. If your electric charge is moving, it is electric current.
Simplest model is: an electric current is actually the flow of electrons, and they MUST flow in a complete loop ... any break stops the flow.
Electric current passes through substances called "conductors", as well as "semiconductors". Conductors include all metals, and any liquid with ions in it.
Any electric generator does.
There's an electric eel but I'm not sure if it is technically a fish :D
no because any current that is incident on the vehicle is protected by the grounding provided by the tyres.
Electric current is a flow of electrons is a measure of the quantity of electrical charge passing any point of the wire in a unit time.And, electric current is measured in ampere (A).Whereas, electric charge is the quantity of electricity that flows in electric currents . And , it is measured in coulomb (C)
Yes. One ampere of electric current means that 6.241 × 1018 electrons per second are passing any given point in a conductor.
Electromagnetic fields form around any current carrying conductor.
Any moving current produces a magnetic field, which is what affects the compass needle.
Heat in an electric wire is mainly caused by the rapid movement and collision of electrons as they flow along it, when an electric current is cut off, the flow is greatly reduced causing a huge drop in temperature.
Potential . . . Always measured as a potential difference between two points. The most practical way to do that is with a voltemeter connected in parallel with any circuit between the two points. Electric current . . . The most practical way to measure current is with an ammeter connected in series in the path of the current.
definitions from the web include: the mechanical device by means of which an electric connection to an apparatus is established. the point of current entry to, or point of current departure from, any conducting component in an electric circuit. So any electric appliance (in a vehicle) has a point at which electricity passes into and out of it in the electric circuit. Those points are the terminals.
Yes. Any electrical current contains energy.
Any electrical generator except solar.
You'll get the most current in the path of lowest electrical resistance, but be aware that any conducting path will allow a current to flow.
A magnetic field is induced around any conductor carrying an electric current.As explained in the Oersted Theory.
" I " stands for electric current and an electric current is a flow of electrons that have been dislodged from atoms and is a measure of the quantity of electrical charge passing any point of the wire per unit time. Note : A common unit of current is the ampere, a flow of one coulomb of charge per second, or 6.24 × 1018 electrons per second.
Not a constant electric current but a changing one will generate electromagnetic waves. First: If you have a lone electron, and it is accelerated in any way, it will send off an electromagnetic wave. This is because a changing electric field generates a magnetic field. It is also true that changing magnetic field will generate an electric field. This is the reason that if you have an electric current, which is generating a magnetic field… Read More
The bulb glows indicating that there is current flow. If there is any ammeter in the circuit, it reads when there is current flow in the circuit
The easiest way to control any electric current to any device is with the inline use of either a manual or electric reistate.
electrons or holes depending on doping, as in any semiconductor.
Any chemical compound which will conduct an electric current when it is liquid state or dissolved in water?
is an electrolyte.
Kirchhoff's Laws hold for any of the circuits because at a given junction the electric current distribute. The law states that the algebraic sum of the current at any junction is zero.
What Happens when a n electric current is produced? When electric charges are made to flow through a wire or similar material, they produce an electric current. When the electric current is produced it become's a continuous flow of electric charges through a material.

Not to any perceivable level. Lead will conduct an electrical current, as will any metallic object.
Electric current is the rate of [http://hyperphysics.phy-astr.gsu.edu/hbase/electric/elecur.html#c2 charge] flow past a given point in an electric circuit, measured in Coulombs/second which is named Amperes through any cross sectional area,which can be measured by Pi*r*r. [1coulomb/second=1Ampere] while Electric current density is the measure of electric charges passing through a conductor in a electric circuit in a constant cross sectional area of 1 meter square.[1Ampere/Meter square]
any gadget won't work, as no current would be able to pass due to lack of electric potential difference
Because wood is an insulator, therefore cannot receive any current
Any voltage can be lethal if enough current is allow to flow. Human skin has a form of resistance to electric current flow however if the skin is moist or wet the resistance decrease to a point where IT WILL BREAKDOWN THE BARRIER AND ALLOW CURRENT FLOW
The resistance used in a voltmeter is extremely high when measuring voltage, which is why the current is low (I = E/R).
Any electric current can be used to separate the hydrogen in water, the question should be. would it be economically viable to do so.
What property makes certain metalloids useful as switches to turn small electric current on and off?
What property makes certain metalloids useful as switches to turn a small electric current on and off?
It has negative energy that is higher than any type of energy told.
A flow of electrons in an electrical circuit is called a current, which is the name given to the amount of electrical charge flowing in a certain period of time. Any total quantity of electrical charge is measured in coulombs. Any flow of electrical current is measured in amps. 1 amp is equal to a flow of 1 coulomb of electrical charge in one second of time.
You can generalize that any device that produces heat uses a larger electric current (and more electric power). Some examples are: Toaster, hair dryer, hair curler, clothes iron. The iron operates on more current, and uses more power, than the shaver.
No! Any object made of wood donot allow electric current to pass through it.
Yes, all batteries are fully charged when the leave the factory.
