Photocells work during the day because they are light-sensitive sensors that detect changes in light levels. During the day, when sunlight is present, the photocell detects the increased light and triggers a response, such as turning off a light or activating a security system.
What else can I help you with?
What happens if gamma rays falls on a photocell?
Gamma rays typically have enough energy to ionize atoms in the photocell material, releasing electrons. This can result in a current being generated in the photocell, which can be used to detect the presence of gamma rays.
In a photocell light energy is converted into?
In a photocell, light energy is converted into electrical energy. When light strikes the photocell surface, photons of light are absorbed, releasing electrons that create an electric current.
How do streetlights work?
solar street lights work by a solar panel.
What does photocell mean?
A photocell is a device that detects light. It works by converting light into an electrical signal, which can then be used to control various applications like automatic lighting systems or cameras.
Can someone use photocell in a sentence?
im not sure what photo cell is so ill just use it in this sentence.
Can you wire a photocell to work at night instead of during the day?
Photocells are designed to work at night when it gets dark and turn off in the morning when it gets lighter. If the photocell is on during the day then it is not working the way it was designed to. Time to get a new one.
Do led floodlights work with a photocell?
A: Photocell and LED cannot work directly because these are different devices. But yes each independently can work as a unit all you need is some buffering.
Will a photocell work using dc voltage?
it creates a dc current
How does a photocell work in a kerosene heater?
A photocell in a kerosene heater works by using light to generate an electrical current. The photocell detects the flame produced by the heater and triggers the fuel pump to continue supplying kerosene. If the flame goes out, the photocell senses the absence of light and shuts off the fuel supply to prevent dangerous fuel leaks or build-up.
How can a faulty photocell be detected?
By covering the photo cell and if the relay coil doesnt work.
How would a faulty photocell be detected?
By covering the photo cell and if the relay coil doesn't work.
How photo cell function or work?
There is a lot of things when you talked about photocell... well in electronics world of terms the main functions of photocell are for sensing which provides limits or safety.Read more: http://wiki.answers.com/What_is_the_function_of_a_photocell#ixzz1lZGBI2wU
Am using a photocell in a 9volts dc circuit will this be enough to produce an output?
A: A photocell is like a variable resistor it will change resistance with light the ratio of dark:light resistance decides the output. So yes it should work with 9volts
Can a photocell work when installed 3ft below a light?
It will if it can not 'see' the light.- ie, if there is a shade or something between it and the light.
What is a work day?
Monday thru Friday
What did Jews do in Concentration Camps during the day?
