POWER SAVER PLANT
Materials Used - Potentiometer, Relay, Bar board,
Transformer etc.
Scientific Theory - In the presence of LDR, the electric
resistance is negligible but in the absence of light, LDR
shows high electric resistance.
The energy following thought LDR is negligible, when
light rays fall on it. We need to magnify this value. In this
models 3npn transistor, BC547 is used to enhance the
energy which intensifies power of the relay & it becomes
active. The pin in contact with it gets altered. In this way
by using this device, other electrical devices could be run.
Relay is an electromagnetic device that starts acting as an
electromagnet with flow of current though it.
Application - 1. Lighting of street light. 2. Auto dipper
control. 3. In parking light as battery saver. 4. As fire
extinguishing equipment.
