A \(5 \,V\) battery is connected across the points \(X\) and \(Y\). Assume \(D_{1}\) and \(D_{2}\) to be normal silicon diodes. Find the current (in \(A\)) supplied by the battery if the \(+ve\) terminal of the battery is connected to point \(X\)
- A \(0.5\)
- B \(1.5\)
- C \(0.86\)
- D \(0.43\)
Answer & Solution
Correct Answer
(D) \(0.43\)
Step-by-step Solution
Detailed explanation
Here only \(D_{1}\) will work and we know for silicon diode, potential drop on \(D _{1}\) will be \(0.7 V\) \(I=\frac{5-0.7}{10}=0.43 A\)
