Question

The reading of the ammeter for a silicon diode in the given circuit is

• A. $11.5mA$
• B. $13.5mA$
• C. 0.0
• D. $15mA$

Answer 1

The correct option is A $11.5mA$

For silicon diode barrier potential is $0.7V$
So, according to Ohm's law we can write,
$I=\frac{3-0.7}{200}$
$=0.0115A$
$=11.5mA$
