Asked in Science, Physics, Flashlights
How a beam of laser light is different than the beam of light produced by a flashlight?
It does depend on the kind of laser, but the main difference is that a laser emits a focused beam of light of the same wavelength (i.e. color) while a flashlight emits light of many different wavelengths, and 'beams' this light by reflecting it using a concave mirror built into it behind/around the bulb. ...
Asked in Electrical Wiring, Circuits, Flashlights
What type of a circuit do flashlights use?
A flashlight is a series circuit. The batteries positive end connects to the flashlights switch. The switch connects to the center pin of the light bulb. The bulb filament is connected to the center pin of the bulb and the outer metal shell of the bulb socket. The shell of the bulb socket is connected to the metal flashlight's body which returns to the negative end of the battery. Turn on the switch and you have light. ...

What makes a wind up flashlight shine what does it wind together to make the energy is it zinc magnets or something else?
i'm not very sure, but i know it has magnets. as for zinc, you will have to see if someone else answers it. Yeah...;. ...
Will flashlight bulbs connected to a battery run down faster if they are connected in a series or parallel circuit?
It doesn't matter, unless we're talking about some bulbs with integrated switching power supplies, in which case it might make sense to offset (distance) them by about (SwitchingFrequency / NumberOfBulbs) Hz, to make the general load appear mostly resistive. But in about 99.9% of the cases, the placement of a load (and a light bulb is a load) does not change the amount of current it uses as it's a property of the light bulb itself. Of course, with LED lights it's...

When were flashlights invented?
In 1896, Joshua Lionel Cowen invented a decorative lighting fixture for potted plants which consisted of a metal tube housing a light bulb and a dry cell battery. It failed commercially, and so Cowen sold his company and patents to Conrad Hubert that same year and turned his attention to building and selling model trains. Hubert renamed Cowen's company the American Electrical Novelty & Manufacturing Company and, recognizing the true potential of Cowen's invention, hired David Misell to produce a tubular flashlight for...

Removing battery acid from a flashlight?
Flush with lots of water, neutralise with weak solution of sodium carbonate. Mario Don't forget to take into account whether or not it is from an alkaline battery. If so, you may need to neutralize with a weak acid rather than a base. Inquire further on another site. -Matt ...
How does a dynamo flashlight work?
