Which fish gives an electric current?
eel fish gives current
When an electric current is passed through neon gas what does it produce?
An electric discharge through neon gas gives a reddish-orange glow which is most commonly used in advertising signs and lamps.
Why touching a bare electricity wire with current flowing through it gives a electric shock. what happens if the body is wet?
When a person touches a bare electricity wire with current flowing through it, the body completes a circuit and the electricity flows through the body, causing an electric shock. If the body is wet, the water acts as a conductor and facilitates the flow of electricity through the body. This can lead to a more severe shock as wet skin has lower resistance than dry skin.
An electric current flowing through a wire gives rise to a magnetic field whose direction depends upon what of the current?
The direction of the magnetic field produced by an electric current flowing through a wire is dependent on the direction of the current. The right-hand rule can be used to determine the direction of the magnetic field relative to the direction of the current flow.
How a switch controls the flow of electric current?
A switch controls the flow of electric current by opening and closing a circuit. When the switch is closed, it completes the circuit, allowing current to flow through. Conversely, when the switch is open, it breaks the circuit, stopping the flow of current. This on/off mechanism enables the switch to control the flow of electricity to a device or appliance.
What current flows in One Direction?
OneDirection = direct current OppositeDirection = alternating current Source=physics lessons and gives exams :)
When electric current flows through a metal wire?
Electrical current doesn't work quite the way that you would think. A simple way to describe electrical current is to imagine a straw filled with marbles. Each marble represents an electron. If you push an electron in one end of the straw, and the straw was full, a marble would exit the other end of the straw. However, while that example gives an idea of what is going on, electricity is actually exactly the opposite of that. An electron is "pulled" out of one end of a conductor, which crates an electron "hole". An electron next to the hole moves into that empty spot, and so on and so on. So, even though you could visualize the electricity moving through the conductor as "pushing a marble", it's really "pulling one out" and marbles are moving to "fill the gap". (This is known as hole movement in electricity). Different metals have different levels of conductivity. The conductivity refers to how easily electrons can move through the metal. The less conductivity, the more "resistance" there is. When electrons are forced through a metal that has a high resistance, heat is generated. This is why the burner on your electric stove gets hot; a lot of electricity is being pushed through a metal that has a high resistance, and therefore gets hot. The electric flow through Metal by the move of Electrons from one place in that Metal to another place.
What actually gives off light in a light bulb?
Electric current through a filament (thin spiral) of tungsten causes it to heat up enough to glow brightly.
If the resistance of an electric circut is 12 ohms and the voltage in the circut is 60V the current flowing through the circut is?
Ohm's law states that V=IR, that is, Voltage is equal to the current through the circuit times the resistance.Manipulating this equation gives I=V/R, so I=60/12 = 5 A
What produce by the flow of electric charge from one area to another?
When electric charge flows from one place to another, it induces a magnetic field. The direction of the magnetic field is found by the right hand rule. To use the right hand rule, put your right hand into a fist with your thumb pointed up. When your point your thumb in the direction of the current, and the direction your fingers gives you the direction of the magnetic field.
Where in Egypt is the Nile River?
It flows from the south to the north through the east of Egypt and the link below gives a map.
What energy does a cooker produce?
It is the same principle as a light bulb. Current flowing through the filament gives off heat and light without consuming the wire. In a cooker you have a type of wire that gets hot when current flows. It may glow red hot depending on the application.
