Question

A p-n junction in series with a resistance of 5 kΩ is connected across a 50 V DC source. If the forward bias resistance of the junction is 50 Ω , the forward bias current is (A) 1mA (B) 2mA (C) 20mA (D) 9.9mA

Tardigrade Admin · Accepted Answer

Total resistance = 50+5000=5050 Ω ∴ Forward bias current i=(50/5050)=(1/101)=9.9mA

Q. A p-n junction in series with a resistance of $5 k Ω$ is connected across a $50 V$ DC source. If the forward bias resistance of the junction is $50 Ω$ , the forward bias current is

$1 m A$

$2 m A$

$20 m A$

$9.9 m A$

Total resistance = $50 + 5000 = 5050$ $Ω$
$∴$ Forward bias current $i = \frac{50}{5050} = \frac{1}{101} = 9.9 m A$
