In the following circuit, the reading in the ammeter is (a) 25.1 mA (b) 22.5 mA (c) 21.5 mA (d) 21.25 mA

Answer: (c). The Si diode is forward biased; it drops about 0.7 V. I = (5 - 0.7)/(200) = (4.3)/(200) A I = 0.0215 A = 21.5 mA So the answer is (c) 21.5 mA.

In the following circuit, the reading in the ammeter is

Show answer and solution

Answer: (c)

The Si diode is forward biased; it drops about $0.7\text{ V}$ .
$I = \dfrac{5 - 0.7}{200} = \dfrac{4.3}{200}\text{ A}$
$I = 0.0215\text{ A} = 21.5\text{ mA}$
So the answer is (c) $21.5\text{ mA}$ .
