Electricity
flashlight
A battery is a source for electricity. A flashlight and a radio are not a source for electricity.
Like a LED flashlight, the electricity is passing the emitter, turned into light.
Yes, all batteries provide direct current.
None, that's why you use batteries
Automobile batteries are STORAGE batteries. They do not make electricity, but store electricity made by something else (usually the alternator in the automobile) until it is needed. MOST flashlight batteries MAKE electricity by a chemical reaction, cannot be recharged, and are used up. (Exception is a rechargeable flashlight battery, such as Ni-Cads) Car batteries also have several cells inside one container, but each flashlight battery is a single cell. Car batteries store much more electrical current than is found in a single flashlight battery. They are also a LOT heavier- imagine carrying a flashlight with a 40 pound battery!
A dynamo flashlight works by producing its own electricity. The flashlight has a crank that is turned by the operator. The crank runs a small generator inside that produces enough electric to run the flashlight.
When the switch is turned on, the circuit is complete (closed) and electricity is able to flow, so turning the bulb of the flashlight on.
