P-N Junction Diode

In the following electrical circuit, the reading in the milliammeter is

(Take knee voltage of silicon diode =0.7= 0.7 V)

Figure

Show answer and solution

Answer: (b)

  1. The diode's p-side is at the battery's positive terminal, so it is forward biased with a 0.70.7 V drop.
  2. I=V−VkR=5−0.7200I = \dfrac{V - V_k}{R} = \dfrac{5 - 0.7}{200}
  3. I=4.3200=0.0215I = \dfrac{4.3}{200} = 0.0215 A =21.5= 21.5 mA
  4. So the answer is (b) 21.521.5 mA.
