In connection with the circuit drawn below, the value of current flowing through $2\ \text{k}\Omega$ resistor is ______ $\times10^{-4}$ A.
Numerical value type. Enter your answer.
Answer: 25
Without the Zener, the 2 kΩ resistor would get $10\times\frac{2}{3} \approx 6.7$ V, more than 5 V, so the Zener breaks down and holds 5 V across the 2 kΩ resistor (they are in parallel).
$$I = \frac{5}{2000} = 2.5\times10^{-3}\ \text{A} = 25\times10^{-4}\ \text{A}$$
