Figure Q3(a) shows the circuit for a 15 V, 1A regulated power supply. The power for the regulator comes from an unregulated supply using a full wave bridge rectifier and a 15-volt transformer having a ripple voltage of IV peak to peak at maximum load current. Transistor Tr, has a current gain of 50, Transistor Tr has a current gain of 150 and leg of 10mA and the Zener diode is a 10V device requiring 20mA for normal operation. If the power supply is operating at full load, calculate the values of all of the voltages and currents shown on the diagram (no resistor values required).
