Question
Calculate the current through the circuit and the potential difference across the diode shown in figure. The drift current for the diode is $20\mu\text{A}.$


Current in the circuit = Drift current
(Since, the diode is reverse biased $=20\mu\text{A})$
Voltage across the diode $=5-\big(20\times20\times10^{-6}\big)$
$=5-\big(4\times10^{-4}\big)=5\text{V}.$
