Can solar cells used in mobile phones?
No, cell phones draw too much power to be supplied by solar cells, unless you used a large solar panel. But you certainly can't build a solar cell into the back of the phone like you would a solar calculator. For example, one web source says a cell phone draws about 1 W. Another web source says solar panels can put out about 1.2 W for 100 cm2 in bright sunlight. So to power the cell phone you'd need a solar panel at least as large as a CD, probably more like a sheet of paper.
Calculator use solar panels why don't cell phone calculators do the same?
Phones with solar would mean that the price of the phone would go up. And phones don't need solar panels because they don't pollute. Also, calculators need a very small charge to run, easily provided by a small solar cell. Cell phones need much more energy than that to power their calls.
How much energy does a calculator need and if it is a solar powered calculator how much energy do the panels in the calculator generate?
The average solar calculator produces between 50 and 100 microwatts. A typical solar cell might produce 20 - 40 microamps at between 2 and 3V.In practical terms, this is an incredibly small amount of electricity. You could easily generate that much electricity with a small hand generator.Graphing calculators (which are never solar) use far more electricity (around 0.3 watts or 300,000 microwatts, which is aronud 4,000 times as much). This is why these calculators are never solar. To use solar cells they would need a solar panel 4,000 times bigger than the one on the non-graphing calculators, and that would be too big to fit on the calculator!
How do you figure out how big of a solar cell you need for a job?
You look at the job you need to do, ie, how many volts and amps, or volts and watts, that you need. Then you look in the catalogs for a solar cell or solar cell array to produce that much power.
How do solar cell support the need for energy?
The solar cell coverts the sun light into energy/electricity
What does a solar cell need to produce electricty?
In order to produce electricity, a solar cell needs sunlight and an electrical circuit.
Are solar powered calculator eco friendly?
Yes. They are considered eco-friendly. Solar powered calculators also save time and money because there's no need to replace any batteries.
Does solar energy need to be processed?
The answer to your question really depends on what you are using the energy for. For example, if you're using solar energy to grow crops then obviously not! If you're trying to harness solar energy for use in, say a home? Then the solar energy will need to be put through a Photo-voltaic cell (Solar panel) and then the electrons that are knocked out of the silicon wafers within the solar panels will travel through wires and then generally into a battery. In some cases the battery is bypassed (ie. a Solar Calculator). One can also have "Passive Solar Collection" which avoids a solar cell at all and is commonly used to heat water at cottages or campsites. Basically a hollow object (pipe usually) is filled with water and painted black. The thermal energy from the sun dissipates into the (generally conductive) object and finally into the water within. Hope this helps!
How do you we make solar electronic bell?
firstly you will need a solar cell 3V to power your electronic bell .after that you can make a 5Khz sine wave geneartor and connect it to solar cell and you should also use a timing and control circuit to cuttoff the bell after some time and when any one press the switch circuit energies and take the power from solar cell and alarm will start.
What are 3 most important things about the calculator?
Features - The calculator should do everything you need it to do, but not much more. You probably don't need a TI-94Plus to balance your checkbook.Reliability - If a calculator doesn't work, it's worthless. Get something built well that will last a long time. Preferably something that runs on solar energy with a battery backup.Accuracy and precision - Once you know what you need it to do, make sure it does it well! If you need 6 decimal places of precision make sure you buy a calculator that can actually handle it (not just display it).
