The equation that you are looking for is I = E/R. Amps = Voltage/Resistance in ohms.

What does a light bulb have to do with an electrical light source?
A light bulb is a source of electric light. In an incandescent light bulb, the glass bulb forms a protective shield around a glowing filament. The air inside the glass bulb is removed, or replaced with an inert gas. Electric current is passed through a thin metal filament (usually tungsten), which causes it to glow white hot, giving out light. The protective bulb stops the filament from burning up, as it has no Oxygen.
Where does the energy for a light bulb come from?
it come from the energy source in the middle of the light bulb he clearly asked what type of energy is it?!
Is a light bulb a soure of light?
Yes, a light bulb is a source of light. When current is going through the filament the resistance generates enough heat that the filament glows, producing light.
What causes Electric shock injuries?
Electric shock injuries are caused by lightning or electric current from a mechanical source passing through the body
If you are running a photoelectric effect experiment and your light source cannot create an electric current which adjustment might cause an electric current to flow?
- select the adequate material for this experiment - switch to a light source with a shorter wavelength - switch to a light source with a higher intensity
What is the filament in lights?
Filament is a thin part of incandescent bulb which is the source of electric light that electric current passes through and heated it until it produce light.
Why does the light bulb not work when the filament is broken?
A light bulb works by passing an electric current through the filament, which is usually made from a high resistance substance such as tungsten. When the current flows through, the filament glows which produces the light. When it burns out, no electricity passes and no glowing occurs. Source: i just know
Is a filament a source of energy?
It is when it is heated by electric power, when it gives off heat and light.

One source of constant electric current is a?
Alah
What is a temporary source of electric current?
A generator can be used as a temporary source of power
What do you understand by electric current?
electric current is the flow of electrons due to external energy (emf) supplied by the voltage source.
