In the figure below, in which configurations are the diodes forward-biased (FB) and in which they are reverse based (RB)? Circle FB or RB as appropriate in the right column. The current in an ideal diode is given by: I = I_0(e^qv/kt-1)

Solution

REVERSE BIAS, BECOZ CATHODE POTENTIAL > ANODE POTENTIAL FORWORD BAIS CONDITION BECOZ ANODE POTENTIAL > CATHODE POTENTIAL. REVERSE BIAS, BECOZ CATHODE POTENTIAL > ANODE POTENTIAL FORWORD BAIS CONDITION BECOZ ANODE POTENTIAL > CATHODE POTENTIAL. REVERSE BIAS CONDITION.
