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 electric current flows through the metal filament of light bulb electric energy is converted to?
Heat and light.
A 9.0 volt battery connected to bulb. if a current of 0.25 Amps flows through bulb what is the resistance of bulb?
V = IR Voltage = Current * Resistance so 9 = 0.25 * R Hence R =36 Ohms
What happens when a battery light the light bulb?
When the switch is turned it completes an electrical circuit. The circuit amperage flows through a high resistance filament in the bulb and it starts to glow. The bright glow from the filament and the reflector behind the bulb is what creates the flashlights beam.
When electricity flows through the metal filament of a light bulb electrical energy is converted to?
Heat, which then produces light.
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 lightbulbs are connected in a series how much current flows through each one?
same current flow in each bulb
What gives out a light if an electric current flows through it?
A light bulb in an electric circuit when electricity reaches it.
What is in a light bulb when it's switch is turned on or connected the electricity flows through what we call?
A closed current
When electric current flows through the metal filament of light bulb electric energy is converted to?
Heat and light.
What type of energy is when you plug in a light bulb?
To plug it in, you use your muscle energy. When current flows through the bulb,electrical energy converted to the heat and light energy in the bulb.
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.
A 9.0 volt battery connected to bulb. if a current of 0.25 Amps flows through bulb what is the resistance of bulb?
V = IR Voltage = Current * Resistance so 9 = 0.25 * R Hence R =36 Ohms
What cause glow of a filament of bulb when current flows through it?
The current causes heat. The heat is high enough to radiate energy in the form of visible light.
What happens when the torch is switched on?
current flows and we have light from bulb....
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.
When current flows in the tungsten filament of a light bulb the bulb converts what?
Electrical energy to heat and light.
