Diode Behavior in AC Circuits Quiz

During the positive half cycle, diodes D1D2 are forward biased and act like closed switches, conducting the current.

During the positive half cycle, diodes D3D4 are reverse biased and act like open switches, not conducting the current.

During the negative half cycle, point B becomes positive with respect to point A, causing diodes D3D4 to conduct while diodes D1D2 do not conduct.
