In the given circuit, the current I through the battery will be
Options
- A2 . 5   A
- B1   A
- C2   A
- D1 . 5   A
Correct answer
D. 1 . 5   A
Step-by-step solution
In the first circuit diagram, the diodes D 1   &   D 3 are forward biased and D 2 is reverse biased(Hence, no current through it). So the circuit is simplified to the second diagram. Hence, the equivalent resistance is R e q = 20 × 10 20 + 10 ⇒ R e q = 20 3   Ω Using Ohm's law, the current is I = 10 20 3 = 30 20   A = 1 . 5   A
