Currents flowing in each of the following circuits \(A\) and \(B\) respectively are

- A 1 A, 2 A
- B 2 A, 1 A
- C 4 A, 2 A
- D 2 A, 4 A
Answer & Solution
Correct Answer
(C) 4 A, 2 A
Step-by-step Solution
Detailed explanation
In circuit \(A\), both \((p-n)\) junction diode act as forward biasing. Hence, current flows in circuit \(A\). Total resistance \(R\) is given by \(\frac{1}{R}=\frac{1}{4}+\frac{1}{4}\)…
