A \(2\,V\) battery is connected across \(AB\) as shown in the figure. The value of the current supplied by the battery when in one case battery's positive terminal is connected to \(A\) and in other case when positive terminal of battery is connected to \(B\) will respectively be
- A \(0.4\, A\) and \(0.2\, A\)
- B \(0.2\, A\) and \(0.4\, A\)
- C \(0.1\, A\) and \(0.2\, A\)
- D \(0.2\, A\) and \(0.1\, A\)
Answer & Solution
Correct Answer
(A) \(0.4\, A\) and \(0.2\, A\)
Step-by-step Solution
Detailed explanation
When positive terminal connected to \(A\) then diode \(D_1\) is forward biased, current \(I \, = \frac{2}{5} \, = 0.4\, A\) When positive terminal connected to \(B\) then diode \(D_2\) is forward biased, current, \(I\, = \frac{2}{10}\, = 0.2\,A\)
