Current=((. 3.5 - 0.5 .)/100)A =(3/100)A=30 mA

Q. In the given figure, a diode $D$ is connected to an external resistance $R = 100Ω$ and an $e m f$ of $3.5 V$ If the barrier potential developed across the diode is $0.5 V$ , the current in the circuit will be

40 mA

20 mA

35 mA

30 mA

$C u rre n t = \frac{( 3.5 - 0.5 )}{100} A$
$= \frac{3}{100} A = 30 m A$
