An LED Characteristics Apparatus is used in physics labs to study an LED’s electrical and optical properties, primarily plotting its Voltage-Current (V-I) curve to find threshold voltage, and its Intensity-Current (P-I) curve to understand how brightness changes with current, using components like a DC power supply, rheostat, voltmeter, ammeter, and often a photometer to measure light output, demonstrating LED efficiency, color, and fast switching in applications from indicators to general lighting.
