Concept / Principle: This project works on the principle of photoconductivity — using an LDR (Light Dependent Resistor).The LDR’s resistance decreases when light falls on it and increases in darkness.This change controls a transistor or relay circuit, which automatically turns ON the LED (street light) at night and OFF during the day. Main Concept:LDR senses … Read more
Concept / Principle: This model demonstrates how wind energy is converted into electrical energy using a wind turbine.When air (wind) blows on the blades, it makes them rotate — this rotation drives a DC motor (acting as a generator) that produces electric current to light up an LED bulb. Scientific Principle:Mechanical energy (rotation of turbine) … Read more
