Calculator Solar Energy

that is, how a scientific calculator works when its battery power is totally down?how it works when it is shown in sunlight for sometime?please give me the mechanism involved in it.

when batt not available the triac is used so the base power switches to solar cell and there if it gets energy it emmitts power to 7-segment and again ur calc is on solar batt. when u replace battreis again the triac actives through batt power.

This video introduces the three solar power calculators available to you on SolarQuotes.com.au - and walks you through which one you should use to ...

I'm doing a test using a calculator solar cell and a basic RadioShack multimeter. When in direct sunlight I'm getting 3.3 volts. The question is on the amperage; I have the setting turned to '2mA' and the number that is showing is 1.35. Is this...

That is correct, you will get some that are slightly higher depending on the LCD display and function. The one on my desk is less than that. You have to remember that the working voltage for a micro chip is extremely low and has to be not to fry...

I am doing a science project and I need to find out if solar panels are an environmentally feasible way to heat a pool compared to the #2 diesel that is currently being used. Is there a calculator that I could use to see how much energy a solar panel

What you need is a solar pool heater. It is a series of plastic panels that you run your pool water through using your existing pool pump. As the water runs through them, they get heated by the sun, just like if you leave a hose in the yard, the...

Are you really saying that you do not know what (solar powered) means?
Solar power is from sun light.

I used to have a solar calculator in the 80's which I thought was great!

I'd love for solar energy to be commercially successful but I just don't see how it can compete in a global market as your energy costs will just rocket up...

I think solar power will one day be perfectly feasible and able to power devices which require a lot less power then they do currently (think of the different power requirement for light between an incandescent lightbulb and quantum dots for

Will it be good if there is a solar energy for mp3/PMP with lithium battery?

It would help if going out whole day as it can be recharge without worrying for low power...

The solar cell would have to be as big as your hand to have enough energy to play music. A digital watch is a little energy.
