Why cesium and potassium used in photoelectric effect?
The ionization enthalpy of K and Cs is less than that of Li and therefore these metals easily lose electrons on exposure to light than lithium.That's the reason potassium and cesium are used in photoelectric cells rather than Cs.
Give two examples of photoelectric cells and explain how they work?
The most common photoelectric cells consist of two electrodes separated by light sensitive semiconductor material. A high voltage source, such as a battery, is connected to the electrodes set up a current even in the absence of light. When light strikes the semiconductor material in the photocell, current in the circuit increases in proportion to the intensity of the light. The current from a photoelectric cell is often used to operate switches or relays, so are often used in automatic door openers and intrusion alarms. This type of photoelectric cells are called electric eyes.
What is the name of RbClO3?
Rubidium hypochlorite is the name for this chemical formula.
What period is the element rb in the periodic table?
Rb is the symbol for the element, rubidium.
What is the formula and name for Rb O?
Rb is rubidium, O is oxygen. They will combine to form Rb2O which is called rubidium oxide.
What is radioisotopes potassium-40 and its uses?
is used in photoelectric cells.
How is rubidium used in photo cells?
i dont really know
What are photoelectric cells?
Photoelectric cells are devices that generate electrical output that is dependent on the amount of illumination. They are used in various mechanical devices to set off alarms or open doors.
What nonmetal conducts electricity and is used in photoelectric cells?
Silicon is my best guess
How do photocells generate electricity?
the photoelectrons released during photoelectric effect are used to generate electricity in photo cells

On what factors does photoelectric current depends?
photoelectric current depends on intensity of light used
Instrument used for changing light to energy?
photo voltaic cells convert light energy to electricalenergy The conversion of sunlight to electricity using photovoltaic (PV) cells, also known as solar cells, is based on the photoelectric effect discovered by Alexander Bequerel in 1839. The photoelectric effect describes the release of positive and negative charge carriers in a solid state when light strikes its surface.
