The reading of the ammeter for a silicon diode in the given circuit is: (a) 13.5 mA (b) 0 (c) 15 mA (d) 11.5 mA

Answer: (d). The silicon diode is forward biased, so it takes 0.7 V. I = (3 - 0.7)/(200) = (2.3)/(200) = 0.0115 A I = 11.5 mA So the answer is (d) 11.5 mA.

P-N Junction Diode

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

Show answer and solution

Answer: (d)

The silicon diode is forward biased, so it takes $0.7$ V.
$I = \dfrac{3 - 0.7}{200} = \dfrac{2.3}{200} = 0.0115$ A
$I = 11.5$ mA
So the answer is (d) $11.5$ mA.
