The diode is reverse biased, but the voltage across it is given as 5 V R2 is in parallel with the diode, so current in R2=(5V /1000 Ω) ⇒ Current in R2=5 mA

Q. What is the current flowing in $R_{2}$ , in the circuit shown in figure? Given : $R_{1} = 500 Ω$ and $R_{2} = 1 k Ω$

0 mA

5 mA

40 mA

15 mA

The diode is reverse biased, but the voltage across it is given as $5 V R_{2}$ is in parallel with the diode,
so current in $R_{2} = \frac{5 V}{1000 Ω}$
$\Rightarrow$ Current in $R_{2} = 5 m A$

Q. What is the current flowing in R2​, in the circuit shown in figure? Given : R1​=500Ω and R2​=1kΩ
