The reading of the ammeter for a silicon diode in the given circuit is :
  1. (A)13.5 mA
  2. (B)0
  3. (C)15 mA
  4. (D)11.5 mA✓ Correct

Answer: (D)

Solution

A silicon diode in forward bias drops about V, so of the V driving the circuit only V is left across the resistor. Ohm's law then fixes the current, A, which is mA.
