2.) To follow up on question 2, let's revisit an analysis you did way back in embedded systems. Let's analyze an LED assuming the forward drop model, where we will assume V, z 2V (LEDS have higher cut-in voltages than a typical signal diode!). Let's assume we are connecting an indicator LED to the output of a microcontroller, which looks like a 5Vdc source when at logic “high". Determine the series current-limiting resistor value required to limit the LED current to 15mA when the microcontroller output is set to logic high.
