Three ideal diodes and resistors connected to the cell of negligible internal resistance is as shown. Find the current passing through the 10 resistor.

Options

  1. A2 A
  2. B1 A
  3. C0.1 A
  4. D0.5 A

Correct answer

D. 0.5 A

Step-by-step solution

The circuit consists of three parallel branches connected to a 10 V source in series with a 10 resistor. We analyze the state of each diode D₁, D₂, D₃ . Branch 1 contains D₁ in forward bias configuration relative to the positive terminal of the battery. Since D₁ is an ideal diode, it acts as a short circuit when forward biased. The resistance in this branch is 20 . Branch 2 contains D₂ in reverse bias configuration relative to the positive terminal of the battery. An ideal diode in reverse bias acts as an open circ
