What sort of energy does a solar-powered calculator use?
Question:
Answer:
Are you really saying that you do not know what (solar powered) means?
Solar power is from sun light.
Batteries backed by a small solar panel (solar alone would be too unreliable)
Photons from a light (sun or artificial) hitting the solar pannel creates electricity to power the electronics
solar energy from sun
Well it uses light from any conventional source which is converted into electricity via a photoelectric system... ;^)
solar takes sun 50%energ acording to wheather
Electrical energy.. the solar cells convert the solar energy from the sun(i.e. photons) into electrical energy and then transmit that to run the calculator
Solar means energy from the sun, the power of electronic is from the movement of electric currence. in the sun ray there are particules exactly eletronics currence.
not only sunlight but also just plain light
They use solar energy. More specifically, they use solar cells. A solar cell is a semiconductor device that converts photons from the sun into electricity. The general term for a solar cell including both solar and non-solar sources of light is termed a photovoltaic cell. Fundamentally, the device needs to fulfill only two functions: photogeneration of charge carriers in a light-absorbing material, and separation of the charge carriers to a conductive contact that will transmit the electricity. This conversion is called the photovoltaic effect, and the field of research related to solar cells is known as photovoltaics.
