What kind of solar cell is the calculator? How much power is it? Generally, some calculators we use have a solar panel on them. What kind of panel is that? How to read its specific information? What's its power? The prawn knows, If you only use solar cells on small household appliances, what kind of solar cells (photocells) would be more suitable to meet the requirements of several hundred milliamps and several watts? The voltage requirement is above 5V and below 12V, the current is about 1a, and the area is not more than 400cm2. Can it be realized? If it can be realized, what type of solar cell is needed?
Generally, there are several types of battery chips. The basic ones are: single crystal 125 (s125) single crystal 156 (s156) polycrystal 125 (M125) polycrystal 156 (m156). In terms of efficiency, the manufacturer sells them according to wattage, but the factory makes them according to the efficiency of different grades of battery chips
How to power the solar panel on the calculator
Meet the light to generate a certain amount of current and voltage for the calculator. When there is no light, the current and voltage can not be generated, so the power can not be supplied~
In short, it is "energy conversion", solar energy into electricity!
Can solar calculator be charged under fluorescent lamp?
Is rainy day, cloudy day, no sun how to do, can charge under the light?
The common solar calculator doesn't have charging function, because it uses ordinary silver oxide button battery inside, which is not a rechargeable battery. It can only use the solar panel to supply power for the calculator circuit in the case of strong light, and then it doesn't use the battery's power, Sunlight, incandescent lamps, halogen lamps, fluorescent lamps and other light sources can generate electricity
Is the solar cell on the calculator useful
The power consumption of electronic calculators is very small now
There are enough solar cells to provide electricity
Generally in the daytime, the indoor light is enough to charge, and the light can also be used
Don't expose yourself to the sun

- 12. In the circuit shown in the figure, the voltage at both ends of AB is u = 8V and remains unchanged. If the voltage at both ends of R2 is U2 = 2V and R1 = 4 Ω, then the current through R1 is 0______ A. If the current passing through it is 0.4A, the voltage at both ends of the conductor must be adjusted to zero______ ．
