Question

The circuit has two oppositely connected ideal diodes in parallel. What is the current flowing in the circuit?

(a) 1.71 A 

(b) 2.00 A 

(c) 2.31 A 

(d) 1.33 A

Answer 1

Correct Option (b) 2.00 A 

Explanation:

In the given, circuit diode D₁ is reverse biased while D₂ is forward biased, so the circuit can be redrawn as

['.' for ideal diodes, reverse biased means open and forward biased means short]

Apply KVL to get current following through the circuit
