What are the 4 forms of energy used for a flashlight?
Chemical (battery), electrical (current), thermal (filament), and radiant (light).
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.
How can you tell there is friction and resistance in a bulb?
Electrical resistance is technically not the same as friction though one could be used as a model for the other. Electrical resistance in a light bulb can be seen by the light that is emitted due to the heating of the filament when current is passed through it (electrical potential is transformed into heat).
Is a light bulb an insulator or conductor?
It is a conductor, but the filament is a resistor : as current flows through the filament, some of the energy is released as heat and light.
What is light produced?
A filament is heated by an electric current and photons are emitted.
What is electrical energy converted into when electric current flows through the metal filament of a light bulb?
Electrical energy is converted into light and heat when electric current flows through the metal filament of a light bulb.
When current flows in the tungsten filament of a light bulb the bulb converts what?
Electrical energy to heat and light.
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.
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 are the 4 forms of energy used for a flashlight?
Chemical (battery), electrical (current), thermal (filament), and radiant (light).
What happens to the electrical energy carried by the current when it passes through the filament of a bulb?
it stays there. the electricity travels back and forth through the filament until you turn the lighbulb off.
What is filament current?
The current supplied to the filament of an electron tube for heating.
What does the filament of a light bulb allows the light bulb to change electrical energy to?
The filament of a light bulb overs enough resistance to current flow, that the filament heats up so much that it will glow and produce visible light.
When the flashlight is on is it static or current electricity?
When the flashlight is ON , electrical current is flowing from one terminal of thebattery, through the light-bulb filament, to the other terminal of the battery.
What is the difference between filament current and tube current?
The current supplied to the filament for heating is defined as the Filament current. whereas When the filament is heated to a high temperature, the electrons are emitted. The flow of electrons form Cathode to anode is the tube Current.
Why do light filament bulbs usually blow when they are first switched on?
because when they are first switched on a large surge of electrical current flow through a cold filament. When you first switch on the bulb the resistance is small, so you get a current surge which breaks the weakened filament. The filament is weakened by repeated heating and cooling from the bulb being turned on and off; which makes it brittle.
Why does a fused bulb not glow?
A fused bulb does not glow because the filament of a fused bulb is broken. Since current can't flow through the filament, it can't get hot enough to glow.
