After solving a circuit with ideal diodes (Vf=0), what check is necessary for diodes initially assumed to be on? Off? We must check to see that reverse voltage appears across all diodes assumed to be on, and we must check to see that forward current flows in diodes assumed to be off We must check to see that forward current flows in diodes assumed to be on, and we must check to see that reverse voltage appears across all diodes assumed to be off
