Document Summary
Figure 1: determine and sketch the thevenin"s equivalent circuit for the output terminals a and b. First it would help to redraw the circuit to a more familiar layout. After redrawing the circuit one should see that circuit elements v1, r1, r2 and v4, r6, r7 have no effect on the thevenin"s equivalent circuit. As well current sources i1 and i2 cancel each other out. Therefore the resulting circuit to determine is shown in figure 1b. Obviously the circuit is very simple and the resulting thevenin"s equivalent circuit is . Rn = rth = 300 (provide a circuit sketch as well) October 23, 2003: the output of the power supply shown in figure 2 has a peak to peak ripple of 300 mv. = vp for of the secondary or 212. 88vp if you. V included the 0. 7 volt drop across the diodes. Therefore the full secondary voltage is 2 x 212. 18 vp = 425. 77 vp.
