Please check my work and if incorrect give me the correct answer A shunt regulator utilizes a zener diode whose voltage is 5.1V at a current of 50 ma and whose incremental resistance is 8 ohms. The diode is fed from a supply of 12 V nominal voltage through a 220 ohm resistor. What is the output voltage at no load? a. 4.8 V b. 4.88 V c. 4.96 V d. 5.1 V V2=6.8 I2=50mA R2=8 Vt=12 R=220 I2=(12-6.8)/(220+8)=5.2/228=22.8 V0=V20+I2rz 6.8+.0228*8=5.28 D is the answer
