PhysicsInteger+4 / -1Question 28 of 90

In connection with the circuit drawn below, the value of current flowing through 2 kΩ resistor is _______ $\times10^{-4}$ A.

Your answer

Answer and worked solution

Official answer: 25

Zener conducts (the 2 kΩ alone would take more than 5 V), so the 2 kΩ resistor sits at 5 V: $\frac5{2000}=2.5$ mA $=25\times10^{-4}$ A.

Answer: 25
