To wire a photocell to multiple lights, begin by identifying the input wires from the photocell, which typically consist of a red (load), white (neutral), and black (line) wire. Locate the electrical junction box where the multiple lights are connected, and find the corresponding wires that supply power to the lights.
Experiment No. 14 Planck''s constant (Photo Electric Effect)
3. Keeping the voltage constant and position of photocell fixed, increase the distance of lamp from photo-cell in small steps. In case note the position of the lamp r on the optical bench and the current I. 4. The experiment may be repeated with other filters (at least 2 filters). Observation:
The photoelectric effect is the process whereby a photon of energy (E=hnu), incident on the surface of a conductor, transfers its energy to one of the electrons of an atom. If the energy is sufficient, the …
