When an AC is connect to a full diode bridge and the bridge outputs to +/- to a load, the V/Z volts/load impedance determines the current. The bridge will alternate like a 2P2T switch with only 2 diodes on at a time out of 4, If the load is grounded and the AC swings +/- around neutral (Neutral) gets grounded at distribution transformer or sometimes at service entrance underground plumbing, then a rectified DC will result.
Diodes only rectify voltage difference between source and load, so if load is parallel RC , current only conducts before the peak voltage for a very short duration depending on % ripple voltage.
