WebThe following symbols show the different components that can be found in an electrical circuit. The resistance of a LDR depends on light intensity. At low light levels, the LDR has a high ... WebJun 2, 2024 · If R1 (the LDR) has a sufficiently low value, the transistor base will be held at a low voltage so the transistor will not conduct. When R1 has a high resistance, current will flow from the R1/R2 junction into the base of the transistor, allowing the transitor to conduct, and lighting the LED.
