Determine the readings of ammeters A₁ and A₂ depicted in the figure. Neglect the resistances of both meters.

Options

  1. A0 , 0.2 A
  2. B0 , 0
  3. C0.2 A , 0.2 A
  4. D0.2 A , 0

Correct answer

A. 0 , 0.2 A

Step-by-step solution

In the given circuit diagram, the positive terminal of the 2 V battery is on the left (indicated by the longer line) and the negative terminal is on the right (indicated by the shorter, thicker line). For the top branch containing ammeter A₁ , the n-side (vertical line) of the diode is connected to the positive terminal of the battery, and the p-side (triangle) is connected to the negative terminal. Therefore, the diode is reverse-biased. An ideal diode in reverse bias acts as an open circuit, offering infinite res
