When electric current flows through the metal filament of light bulb electric energy is converted to?
Heat and light.
When is gravitational energy converted into kinetic energy and then into a electrical current?
Hydro-electric powerplant
Why is the filament inside an electric lamp made very fine?
The filament is fine so that its electrical resistance can be quite high. It is also long, for the same reason. Usually it is coiled up to fit the length in the lamp. The heating effect of electric current is proportional to the current squared, time the resistance (I*I*R). Most of the effect is due to the current. The current through the filament must be limited to stop it melting. Adding resistance will do that. Taking resistance away increases heating. So, a low energy lamp has a very thin filament and a high energy lamp will have a thicker filament.
Why is the filament thinner than the copper wire used in circuit wiring?
Filament is thiner than copper hence it dode offers very low resitstance to electric current flowing through it. Therefore heat energy generated with filament during current flow is converted to light. It is possible generate light with lesser power consumption . This lower power requirments is possible due to lesser specific resistance of filament compared to copper.
What is the flow of electrical charges called?
It is called an electric current.
When electric current flows through the metal filament of light bulb electric energy is converted to?
Heat and light.
Why does a light bulb filament get hot when electric current flows through it?
That is the result of resistance in the wire. In energy terms, some of the energy in the electric current is converted into heat.
How does a electric current flow through a light bulb?
The electrical current comes into the bulb from the metal side,flow through the filament ,and out the tip.
When is gravitational energy converted into kinetic energy and then into a electrical current?
Hydro-electric powerplant
How do you use Electric Current in a sentence?
Here are a few examples... - The electrical current is monitored. - The current of electricity is measured in volts. - The electrical current of telephone wiring is 82 volts. They may not be worded the same, but they have the same initial meaning.
What is bulb and its proccess?
A light bulb is an electric light that uses the process of a filament wire that is heated to produce an electrical current. When the electrical current passing throught the light bulb it produces light.
What happen to an electric current after it passes through each bulb?
There is a piece of filament in every light bulb, which has so much friction that when the electric current passes through it, heat energy is produced. This heat energy is then converted to light energy.
What is the energy conversion in an electric toaster?
Electrical power in the form of a flow of current across a voltage difference is converted into heat energy by vibrating the electrons and atoms of the filament. Due to the heat, it gives out orange-red light. Thus it can be said that an electric toaster gives out heat energy as well as light energy.
What is the main type of energy transformation that occurs in the filament of a light bulb?
Electrical energy (the electric current) is transformed into thermal energy (by heating the filament to incandescence), and this thermal energy creates electromagnetic energy in the form of light.

Electric current is defined as what?
Electric current is defined as the movement of electrical charges.
What is light produced?
A filament is heated by an electric current and photons are emitted.
