Ques. 1JEE Main 2025, 23 January (Evening Shift)

What is the current through the battery in the circuit shown below? [figure]

  1. 1.5 A
  2. 0.25 A
  3. 1.0 A
  4. 0.5 A

Answer

(4) 0.5 A

Solution

The long plate (positive) of the cell feeds the p-side of both diodes both are forward biased and act as wires.
