The current I in the given circuit will be :
  1. (A)10 A✓ Correct
  2. (B)20 A
  3. (C)4 A
  4. (D)40 A

Answer: (A)

Solution

The given circuit is a balanced Wheatstone bridge (the ratio of resistances in the two arms are equal), so the middle resistor carries no current and can be removed.

The equivalent resistance is .

Using Ohm's law: .
