Applying loop equation i=(4.5 - 0.5/1000)=4 mA

Q. A $P - N$ junction diode connected to a battery of e.m.f. $4.5 V$ and an external resistance of $1000 Ω$ . What is the value of current in the circuit, if potential barrier in the diode $= 0.5 V$

$4 A$

$4 m A$

$5 A$

$5 m A$

Applying loop equation $i = \frac{4.5 - 0.5}{1000} = 4 m A$
