Figure 3.9 Bridge rectifier. The top of the transformer secondary connects to the anode of D1 and the cathode of d3. The bottom of the winding connects to the anode of D2 and the cathode of D4. The anodes of D3 and D4 connect together and go to ground. The cathodes of D1 and D2 connect together and go through the load resistor, RL, to ground. There are terminals on each end of RL.
