What material will allow electricity to flow between the battery and the light bulb?
A metal wire is typically used to allow electricity to flow between the battery and the light bulb. Metals are good conductors of electricity due to their free-flowing electrons that can carry electric charges. The wire completes the circuit, allowing the electric current to travel from the battery to the light bulb, providing power for it to illuminate.
What is the thin wire is an electric bulb that glows called?
The thin wire in an electric bulb that glows is called a filament. It is typically made of tungsten and glows when electricity passes through it, producing light.
Who is the first scientist who discover a bulb?
Thomas Edison is credited with inventing the first commercially practical incandescent light bulb in 1879. However, Sir Humphry Davy created the first electric light in 1802 by passing an electric current through a platinum filament.
The difference between wet-bulb and dry-bulb temperature is called?
The difference between wet-bulb and dry-bulb temperature is called the Wet-Bulb Depression. It is a measure of air humidity, with a larger depression indicating higher humidity levels.
Why does a bulb glow when electric passes through it?
The filament in the bulb has resistance. The current flowing through the resistance of bulb causes the filament to dissipate energy in the form of heat and light. The filament is actually glowing white-hot because of the energy it is dissipating, thus giving off light.
Why does electric bulb become dim when electric heater in parallel circuit is switched on?
The electric heater draws some of the electrical current in the circuit, which reduces the current available for the electric bulb. This leads to a decrease in the brightness of the bulb as it is receiving less power.
Can you name three convection currents?
The Mantel and CoresOne is RadiatorKettle, Electric Heater and Light Bulb
Do all the other lights go out when you turn off an electric light bulb in our home?
No, because devices (light bulb, heater, TV set, and so on...) in our home are connected in parallel.
What is the difference between a filament of a bulb and an element of an electric heater?
The heater element is thicker wire, and has lower resistance. It still has enough resistance to glow red hot (producing heat) but does not glow white-hot and very brightly like a light bulb filament. Also, it lasts almost indeifnitely. whereas the light bulb filament has a finite life - it will "burn out" sooner or later.
Why it is impractical to connect an electric light bulb and an electric heater in series?
It would not work because when two things are in series the same current has to pass through both. Normally an electric light takes much less current than an electric heater and therefore the light has more resistance. Most of the voltage would appear across the light bulb, so you would have a slightly dimmed bulb and a heater giving out very little heat. It would work if both devices were identical. Electricity supplies use a constant voltage, e.g. 120 v or 240 v, and all applicances are connected in parallel across the supply.
How is a light bulb similar to a heater?
A light bulb similar to a heater in that they both produce heat when in operation.
What is a electric bulb in short?
a bulb is light bulb
Is electric energy converted to heat energy or light energy?
Yes, electrical energy can be changed into thermal (heat) energy. Light is electromagnetic energy, and electricity can be changed into light energy. We know that a resistance heater changes electrical energy into thermal energy. An electric range does this, as does an electric space heater. We see electrical energy changed into light in fluorescent lights.
Any three parts of an electric bulb?
Three parts of an electric bulb might include the filament, the actual bulb, and the base.
Which came first the telephone or the electric light bulb?
The electric light bulb came first but was patented later that the telephone was.
What is the similarity between a clinical and laboratory thermometer?
both of them contain mercury and both are used to check temperature.
Explain why an electric bulb becomes dim when an electric heater in parallel circuit is made onWhy dimness decreases after some time?
this happen due to sudden amount of voltage drop in the main feeder due to large current drawn by the heater , so this drop in voltage will let the bulb operate by avltage of a mount (V-Vd) [where V represent the supply voltage and Vd represent the voltage drop in the main feeder of the circuit] , which is less than the voltage before the heater is connected and due to this situation the current passes through the wire of the bulb will be less and therefore the brightness of the bulb becomes dim.after a while the wire of the heater will has high temperature which increase its resistance and due to this the current drawn by the heater will decrease than the current at the first time , therefore the drop in voltage will also decrease , which implise increase in current drawn by the bulb and therefore the dimness decrease .
