Abstract

The rapid development of technology poses challenges in electronics education, particularly in students' ability to observe and test electronic components such as transistors. This study aims to systematically observe and measure transistor characteristics by identifying codes and numbers on the transistor body, determining voltage parameters, and analyzing LED lamp load conditions. The research employs an experimental approach with direct measurements using a multimeter and power supply coupled with circuit components. The BC 547 transistor base terminal functions as a switch, with voltage inputs ranging from 2 Vpp to 4 Vpp applied incrementally (2, 2.5, 3, 3.5, and 4 Vpp). In closed switch configuration, 2 Vpp produces 0 A current with lamp off, 2.5 Vpp yields 0 A with dim illumination, while 3-4 Vpp generates 0.02-0.12 A current with bright to very bright conditions. In open switch configuration, all voltage levels produce 0 A current with lamp remaining off, confirming transistor's dual function as amplifier and switch. This research contributes to basic electronics practical learning, provides measurement-based experimental procedures, and assists technicians in transistor identification within electronic circuits.
