In the given figure, a diode DD is connected to an external resistance R=100ΩR = 100Ω and an emfemf of 3.5V3 . 5V If the barrier potential developed across the diode is 0.5V0 . 5V, the current in the circuit will be

In the given figure, a diode D is connected to an external resistance R = 100Ω and an emf of 3 . 5V If the barrier

Options

  1. A40 mA
  2. B20 mA
  3. C35 mA
  4. D30 mA

Correct answer

D. 30 mA

Step-by-step solution

Current = \dfrac{( 3.5 - 0.5 )}{100}A<br/><br/><br/><br/>= \dfrac{3}{100}A = 30mA
