Question

A junction diode is connected to a $10V$ source and $1K$$\Omega$ rheostat. Potential barrier is $0.5V$. The current ion the circuit is

• A. $9.5A$
• B. $9.5$$\mu A$
• C. $9.5mA$
• D. $95A$

Answer 1

The correct option is C $9.5mA$

Given:
$V=10V$
$V_D=0.5V$
$R=1K\Omega =1000\Omega$

The current in the circuit is
$I=\frac{V-V_D}{R}$

$I=\frac{10-0.5}{1000}$

$I=\frac{9.5}{1000}$

$I=9.5\times {10}^{-3}=9.5mA$
