Electricity has to pass through the filament which, when it gets hot enough from resistance to the current, begins to glow and give off light.
The size of the light bulb needed for a fridge is typically a small appliance bulb, usually around 40 watts.
Electricity is needed to light a light bulb because the flow of electrons through the filament inside the bulb generates heat and light energy. This energy causes the filament to emit light, thus illuminating the bulb. Without electricity, there is no source of energy to power the light bulb.
No, a light bulb will not glow if placed in milk. Milk is not a conductor of electricity, so it will not allow the flow of current needed to power the light bulb.
It takes a # 194 mini bulb.
The switch is not needed.
Eight people are more than enough to change a light bulb. Usually one person is needed.
No, an apple does not contain enough energy to power a light bulb. A light bulb requires electricity to produce light, which usually comes from a power source such as batteries, generators, or electrical outlets. The energy stored in an apple is not enough to produce the amount of electricity needed to power a light bulb.
A light bulb is manufactured to operate on a specific voltage. The voltage can be a low as needed and the manufacturer will compute the size of the filament that is needed for a specific wattage. If you are referring to a threshold voltage then that is another question that needs to be asked.
To make a light bulb light up, you need a closed electrical circuit. This circuit typically consists of a power source (such as a battery or outlet), wires to carry the electricity, and the light bulb itself. When the circuit is complete and electricity flows through the bulb, it will produce light.
Electricity powers the light bulb by flowing through a filament inside the bulb, which causes it to heat up and produce light. The filament is typically made of tungsten, which has a high melting point and can withstand the heat needed for light production.
In a simple system, such as a light bulb connected to a battery, energy is transferred through electrical currents. When the battery is connected to the light bulb, it provides the energy needed for the bulb to emit light. This energy transfer occurs as the electrons flow through the wire from the battery to the light bulb.
