Question

3. For the regulated power supply shown in Figure 5-3, which is a full-wave bridge rectifier containing ter combined with a Zener diode voltage regulator, determine the load voltage VI, load current Ir, source current Is, Zener current Iz and the ripple voltage at the input and output of the regulator, and r(p-p)y respectively, and the ripple frequency fr a fil- VL Ir.
