Web2 de abr. de 2024 · If the LED is open, no current can flow through the current limiting resistor (1k2), there is no voltage drop from Vcc = 5V. So the voltage at the test point is ~=5V. If the LED is short circuited, the voltage across the LED is zero, so the test point is at the same level or ground, also ~= 0V. But there is a catch here.
