1N456 SI Signal Diode 25V 100mA Very Low Leakage (10 pack)

in this video we're gonna work on solving some diode circuit problems so for each of these circuits calculate the output voltage and the current flown through the resistors now the first thing we need to determine is if the diode is on or in the off state the silicon diode requires a voltage of about point seven volts to activate it so there's enough energy in these batteries to turn on the silicon diode now for the circuit on the Left the current which flows from the positive terminal to the negative terminal that is the conventional current keep in mind electron flow is in the opposite direction but in the direction of conventional current this silicon rece I mean the silicon diode will be on the other one is in the opposite polarity it's not connected properly so this particular diode will be off so there's nothing we could really do with this circuit so the output voltage will be ze
