#4 Draw the schematic of a digital (on/off) circuit using an N-Channel MOSFET to control an LED. With a power supply voltage of +12V, when the input voltage is zero, the

LED is off and when the input voltage is +5V the LED is on. Show the equation used to determine the series current limiting resistor. (10 points) Assume the forward voltage of the LED is 2.5V and choose a reasonable value for LED current.
