How does a photocell convert light into electrical energy?
Light heats a photocell, and the difference in temperature creates an electric current(:
Is photocell used in calculator?
Yes
What does photocell mean?
light of a cell
What is alternating current produced by?
Dynamo
When is current produced?
current is produced when there exists a potential difference between two points and d electrons move between these points.
How does a photocell convert light into electrical energy?
Light heats a photocell, and the difference in temperature creates an electric current(:
When light strikes a photocell does the resistance increase or decrease?
When light strikes a photocell, the resistance decreases, allowing current to flow more freely.
Will a photocell work using dc voltage?
it creates a dc current
What ways can voltage be produced?
Voltages are produced by converting one form of energy into electrical energy. Mechanical energy can be converted into electrical energy (voltage and current) by moving a magnet or magnetic coil in proximity with a stationary coil, connected to an electrical circuit. A voltage can also be produced with a chemical reaction. Batteries and fuel cells convert energy in specially designed cells, where a chemical reaction causes a voltage to exist across two electrodes implanted at two different parts of the cell. A voltage can be produced by the interaction of light on a photocell. The photons of light interacting with atoms in the photocell, cause an electron to be ejected. The special design of the photocell causes this to occur in such a manner as to produce voltage across the cell. A voltage can be produced by subjecting a thermocouple to differential temperature. A thermocouple is a relatively simple device composed of two dissimilar metals, joined together at what is referred to as a thermal junction. If one side of the junction is warm, relative to the other side of the junction, a voltage exists across the junction.
Where do you buy a 6 volt replacement photocell?
You can buy 6v photocell dusk to dawn switches from Acetek photocells
How do sensors sense light and dark?
A: A photocell has the property to change resistance as photon hit its surface that cause a change in resistance with current is flowing a voltage is generated
How does a roof affect the position of a photocell?
the roof is slanted so you will need to put your photocell on the side of the roof where the sun is shining
What is the tranducer used in a smoke detector?
There are two types:ionization - a tiny piece of Americium ionizes air in the transducer. a tiny electric current passes through this ionized air. smoke deionizes this air, reducing the current and tripping the alarm.photoelectric - a light and photocell in the transducer looks for smoke. smoke reduces the light falling on the photocell, tripping the alarm.

What is the current produced by dry cells?
Alternating current.
Which current is produced by earth batteries?
alternating current
