Quite a few devices can be used directly as DC electric generators. This question seems to be structured to ask for a selection from a list - but the list is not provided.
electric generator is a device which can send amount of electricity to different places
A generator in a power plant converts rotating kinetic energy into electrical energy An electric motor is a device which changes electrical energy into kinetic. For example-- Fans could be like electric energy to kinetic energy...
An alternator and a dynamo could both be called generators.
if you need it for a 120 Volt outlet I would go to radio shack.. otherwise, you could either get a gasoline powered generator/ engine.. Or maybe a car audio amplifier would help.. you could get a capacitor.. Tazer gun..
It is possible, but in general it would be fairly pointless unless you want a very specific type of application The simplest way to do what you're proposing would be to have a motor spin an axle, and connect that axle to the generator's input. But because of the fact no system is loss-less you would be losing energy to friction and hysteresis and resistance you would be losing energy if you have a motor power its own generator. On the other hand this device could then be connected to a battery bank (through proper voltage regulators and a rectifier) and it would be possible to either charge the cells (by connecting the generator and spinning the axle) or run the motor (by discharging the cells through the motor). This is a little like the principle behind regenerative breaking in an electric car. Also, every generator is ALSO a motor, in a way, it simply depends how it's hooked up. Any AC electric motor could theoretically be turned into a generator.
It is better if you could use an electrical supply. The noise of the generator, interruption of power when the generator stops from lack of fuel and unstable voltages from loads being picked up and dropped are some of the drawbacks of using a generator.
When using an electric generator in the home it is important that the extension cords and cables that connect to the generator are strong enough to accept the electrical charge. Cords that are unrated or that are not designed for heavy-duty use could quickly overheat and cause a fire. It is also important to keep any flammable fuel away from the generator and the cords to prevent stray sparks from igniting the fuel.
Electric generators are available from online from various retailors. You can a try Lowe's or Home Depot but you can also look for direct retailors such as Electric Generators Direct.
When Ted took his brother camping so they could watch movies, he took an electric generator, so that the television set and the DVD player would operate in the forest.
Using a normal electric plug instead of a transformer depends on the voltage and current requirements of the device you're powering. If the device operates at a different voltage than the standard household supply (like 120V or 240V), using a plug without a transformer could damage the device or create a safety hazard. Transformers are essential for stepping down or stepping up voltage to match the device's specifications. Always check the device's voltage requirements before connecting it directly to an outlet.
Not directly. The photosynthesis is a chemical process that cannot generate an electric current. You could potentially burn the plant matter to release the energy to turn a generator, but that would not be practical for a calculator.
First ac has to be rectified into dc and then that could be stored in a secondary cell in the form of chemical energy.
