The series resistor r provides a voltage drop and we calculate its value from the formula below. Meaning that with for example a 6v power source and a diode voltage drop of 11 the voltage at the exit of the or gate would be 49v. How Schottky Diodes Work Eagle Blog Zener Diode As Voltage Regulator Tutorial Shockley Diode Calculator Omni If forward current flows though. How to calculate diode voltage drop . With positive voltages up to 12v ie. Step 2 assume the diode is on and consider it is ie is represented by an independent dc voltage source with a value of 06 v. Silicon diodes have a forward voltage of approximately 07 volts. If vd is lower than 06 volts accept the solution. Thus you can use ohms law to find the current through the resistor and diode but to do that you need the voltage across the resistor. Calculate vd the voltage at the dio...
