WebWhen you assume the (ideal) diode is off, you're stipulating that there is zero current through - an ideal diode that is off is an open circuit. When you solve for the voltage across the diode using KVL, you write: V d = V i n − V o u t = V i n = 10 V i.e., the voltage across the resistor must be zero since there is zero current through. WebFeb 18, 2024 · Method 1: The Diode as a Switch The most painless (and least accurate) way to analyze diode circuits is to pretend that the diode is a voltage-controlled switch that functions as a perfect one-way valve for electric current. If the voltage across this “switch” is greater than 0 V, current flows freely, without any resistance or voltage drop.
