I. Calculate the current through the 10. k Ω resistor shown in Fig. T.221. Assume thatthe Zener diodes have ideal voltage-source characteristics.lAns. 1 mA]60 Ω10 knsvずv-Fig. T.2.2.1

Answer»

since zener diode here is in reverse biased form , so maximum potential around 10kΩ is the sum of potential of both the zener diode = 5+5 = 10v

now current through 10kΩ = v/R = 10/10kΩ = 1mA.
