Consider the circuit shown. A string of three diodes is used to provide a constant voltage of about 2.25 V. Calculate the percentage change in this regulated voltage ((ΔVo/ΔVi) x 100) caused by (a) a 10% change in the power supply voltage, and (b) connection of a 1k load resistance.

Q4. In the given circuit, a string of three diodes is used to provide a constant voltage of 2.25V. Calculate the percentage change in this regulated voltage caused by: a) ± 15% change in the power supply voltage (no load connected) b) Connection of a 2 kΩ load resistance
QUESTION 2 (25 marks) -(CLO1-PLO1) A circuit is shown in Figure 1 below. The diodes are germanium type with forward biased voltage of 0.3 V. V1 is a variable voltage source while V2 supplies voltage of 5 V. Figure 1 (a) Calculate the diode currents ID2 and ID1, if V1 is set to 5V. Determine the setting of V1 so that the diode currents ID2 = ID1 (b) By changing the diode to silicon type diode, calculate the diode currents ID2 and ID1, when V1 is set to 2 V
