What did Thomas Edison contribute to the world?
Actually he did not invent the lightbulb, he only improved on it making it practical and inexpensive. His real impact on electrical technology was to invent the infrastructure (e.g. large generators, distribution grid, electric usage meters, fuse boxes, light switches, light sockets) needed to support those lightbulbs so that people could depend on them working when needed. The creation and maintenance of this infrastructure for the first time was of far greater significance than the invention of lightbulbs or his perfection of lightbulbs.
Can a light bulb cause fire?
Yes it can. If a light bulb breaks, the exposed filament will burn out within a couple of seconds and can ignite something with the spark when the filament breaks. Special bulbs can be made for explosive environments to minimize the risk of ignition, such as lighting at a refueling station. A light bulb can also be in close proximity to a combustible substance when it is operating and can cause a fire by making the combustible substance too hot. Florescent lights are less likely to cause fires because they run cooler and are safer in hazardous environments where a conventional light bulb would not be good. <<<>>> No. The filament will burn out in milliseconds not seconds and not enough time to ignite anything in a normal atmosphere. Special bulbs are not made for explosive environments it is the fixture that the bulb goes into that have the explosion proof rating. Fluorescent lamps in hazardous environments again are protected by the fixture that they are installed into. If the light bulb breaks the filament will be exposed to oxygen in the air and burn itself open. It is when the light bulb is in close proximity to a combustible substance when it is operating, that a fire hazard becomes a reality.
What is a rocker arm in a DC motor and what will happen if the rocker arm connections are changed?
A rocker arm holds a carbon brush. In other words it is a carbon brush holder. Changing over the rocker arm connections is the same as changing over the armature connections and will make a DC motor turn in the reverse direction assuming that the magnetic orientation of the motor's field stays the same.More detailDC motor having a field windingIf the stator's field is created by a field winding and that winding's connections are changed over at the same time as the armature's connections are changed over, then the DC motor's direction of rotation will be the same as before.If the stator's field is created by a field winding and that winding's connections are not changed over at the same time as the the armature's connections are changed over, then the DC motor will turn in the reverse direction.DC Motor having a field created by a permanent magnetIf the stator's magnetic field is created by a permanent magnet and the orientation of that magnet is reversed at the same time that the armature connections are changed over, then the DC motor's direction of rotation will be the same as before.If the stator's magnetic field is created by a permanent magnet and the orientation of that magnet is not reversed at the same time as the armature connections are changed over, then the DC motor will turn in the reverse direction.
Who Developed electic light bulb?
Bob the builder!
Element used in light bulb filament?
That depends on the bulb, and the time frame. The first bulbs had carbon filaments. Certain bulbs used in control devices have iridium filaments. Modern grocery store incandescent bulbs have tungsten filaments.Tungsten, because of its very high melting point.
How has the light bulb evolved and changed over time?
The light bulb has evolved and changed over time through advancements in technology and materials. From the invention of the incandescent bulb by Thomas Edison in the late 19th century to the development of more energy-efficient options like LED and CFL bulbs, the light bulb has become more durable, longer-lasting, and environmentally friendly. These advancements have also led to improvements in brightness, color options, and smart features, making lighting more customizable and efficient.

Replace number plate light bulb on Citroen Picasso?
License plate like bulb, on a Citrogen Picasso, can be changed by pushing the bulb in and turning at the same time. The bulb will come out. Insert the new bulb.
Has the speed of light changed over time?
No, the speed of light has remained constant over time according to current scientific understanding.
Why Charles Francis Brush built the light bulb?
in that time they were no light so he build the light bulb

How do you know how to change the front light bulb on a 2002 Malibu car?
Remove the light bulb connector from the light. Take hold of the light bulb, push in and turn at the same time. The light bulb will come out. Reverse the process to install the new light bulb.
How do you replace fog light bulb on Mitsubishi Montero Sport?
Drive it into your favorite oil change station and tell them your light is out. Within 15-minutes they'll do the work for you. Last time I needed a bulb changed it cost me about $10 for parts and labor.
Did peter cooper hewitt invent the fluorescent light bulb?
Yes, Peter Cooper Hewitt did invent the first mercury vapor lamp, which was a precursor to the modern fluorescent light bulb. The technology evolved over time to what we now commonly refer to as the fluorescent light bulb.
